Particles then bunch under the action of the acoustic radiation forces. [40] An evidence of hypersound amplification by stimulated emission of phonons emerges, in a system where the inversion of the electron populations for phonon-assisted transitions exists. Therefore, amplification and cooling occur around a tunable line center, in contrast with some cavity optomechanical phenomena. Therefore, we have a stimulated emission, which means a lot of energy (e.g., acoustic radiation, phonons) is released at the same time. Any interactions of its electric dipole with normal electric field, lowers one of indirect exciton sub-levels and in sufficiently strong electric fields the moving indirect exciton becomes the ground excitonic level. Large crystals have been found at the Montana Megaliths which are hexagon shaped just like the computer motherboard towers in the circuit pattern. See. The vibration energy of the lattice can take discrete values for every excitation. The corresponding parts in a SASER device are the excitation or pumping mechanism, the active (amplifying) medium, and the feedback leading to acoustic radiation. A SASER device mimics this procedure using a source-pump to induce a sound beam of phonons. The set-up needed for the implement of sound amplification by stimulated emission of radiation is similar to an oscillator. This increase of the amplitude is observed for those biases in which the energy drop per period of the superlattice is greater than the phonon energy. Note the concentric circles and the spirals are painted in, See Planetary Grid System Map POINT #18 on, Most astounding of all, the team discovered that living. 30 acres. Consequently, the pumping of these transitions has to be very intense so as to obtain a steady laser generation. The medium where the amplification takes place consists of stacks of thin layers of semiconductors that together form quantum wells. There have been no tools, pottery or other signs of human habitation found on site. This means that there are more excited electrons than electrons in the lowest energy state in the system. This means that the lasing transition must be allowed by momentum and energy conservation laws to generate in a steady form. Bubbles with resonance frequencies close to the pump frequency make the main contribution to the gain of the useful mode. Akimov, W. Maryam and M. Henini. Namely, in a mathematical point of view, if an electric field is applied to a superlattice the relevant Hamiltonian exhibits an additional scalar potential. This means that, since bosons with the same energy can occupy the same place in space, phonons and photons are force carrier particles and they have integer spins. The pumping is created by radial mechanical pulsations of a cylinder. Therefore, their interaction with the electronic subsystem is weak. a light beam or voltage) can help to the excitation of an electron. This stands in similar paths with the laser where a coherent light can build up by the concerted stimulated emission of light from a lot of atoms. [11][12] We could also imagine a concept where the excitation of an electron briefly leads to vibration of the lattice and thus to phonon generation. The pressure of a wave pump in the system leads to both the appearance of a backward wave and a dynamical instability of the system. The differences between the two devices suggest that SASERs could be made to operate over a wide range of frequencies. Kent and his colleagues R.P. Tekh. In a laser, the active medium is placed between two mirror surfaces (reflectors)of a Fabry–Pérot interferometer. These are critical pieces of the puzzle that point to advanced ancient technology using sound and SASER technology by the ancient civilisations that occupied this part of the world as far back as 300,000 years ago. ... Spiral of life can be found in ancient art work all around the world. A directed-energy weapon is a ranged weapon that damages its target with highly focused energy, including laser, microwaves, and particle beams. For typical conditions of the optical micro-resonators, the photonic molecule behaves as a two-level laser system. The importance of this, lies on the fact that electric and in-plane magnetic fields normal to coupled quantum wells, can control the dispersion of indirect exciton. How could they have learnt such amazing abilities and a … Using SASERs to manipulate electrons inside semiconductors could theoretically result in terahertz-frequency computer processors, much faster than the current chips.[3]. phonon) it interacts with another excited electron to release its energy too. This cup is … This concept can be more conceivable by imagining it in analogy to laser theory. The Art House Contemporary Library is an abridged collection of knowledge gathered from 7+ years of consciousness research.The purpose of this library is to bring people into full awareness of the fascinating potential of the human consciousness on a personal level as well as for the collective mind. According to Michael Tellinger, the stone circles were part of an ancient system to produce sound waves into the atmosphere by using a device, (sound laser beam) what we call today a Saser, needed for gold mining. It readily releases energy to return to its stable low energy state. The approach uses intermodal coupling, induced by radiation pressure[33] and can also provide a spectrally selective mean to detect phonons. Beardsley, A.V. More than a Sip and You Feel a Drip: A Morbid Motif for the Crafty Pythagoras Cup. A device was first experimentally demonstrated in the Gigahertz range in 2009.[8]. [citation needed], SASERs could have wide applications. Nevertheless, there is a bizarre inversion between the roles of the active medium and the cavity modes (laser field). The aim here is to check if the operation of this scheme with a rather moderate pumping rate can hold against the fact that excitons in coupled quantum wells have low dimensionality in comparison to phonons. We note that, the difference in energy of the photon lasing levels has to be at least smaller than the Debye energy in the semiconductor. Therefore, to proceed to an understanding of a SASER design we need to imagine it in analogy with a laser device. This aims to more simple numerical estimations. Every one of this "excitation packages" is called phonon. On this basis, physicists were searching for materials in which stimulated emission rather than spontaneous emission, is the dominant decay process. With modern technology, if a difficult route like Khunjereb pass can be made commercially viable,, Karakoram trade route can certainly be made into India’s grand gateway for trade and commerce to … Photons have negligible wave vectors and therefore the band extremes have to be in the same position of the Brillouin zone . In indirect exciton, electrons and holes are in different quantum wells, in contrast with direct exciton where electrons and holes are located in the same well. The energy gap in a semiconductor under the influence of pressure or magnetic field slightly varies and thus does not deserve any consideration. these cave paintings found in Cuba are exactly like the glyphs found in the underwater city off the coast of Cuba. The generation of coherent phonons in a double-barrier semiconductor heterostructure was first proposed around 1990. On the other hand, the group from the University of Nottingham took a different approach. The basic necessary condition for the generation of a laser radiation is the population inversion, which can be achieved either by exciting atoms and inducing percussion or by external radiation absorption. Metaphysics Videos you watch may be added to the TV's watch history and influence TV recommendations. Compound optical microcavity systems provide beneficial spectral controls. Relaxation of an electron from one of the upper states may occur by emission of either a photon or a phonon. Since, the initial spatial distribution of the particles is uniform, the waves emitted by the particles are added with different phases and give zero on the average. Therefore, by pumping energy into the system we can have a stimulated emission of radiation—which means that the pump forces the system to release a big amount of energy at a specific time. Upon the addition of electrons, short-wavelength (in the terahertz range) phonons are produced. Briefly, as an electron hops from one quantum well to another neighbouring well it produces a phonon. Note that interband transition is the transition between the conduction and valence band. At some particular times, some electrons get excited while others lose energy in a way that the average energy of system is the lowest possible. Since the electrons are confined to the quantum wells existing within the lattice, the transmission of their energy depends upon the phonons they generate. series 92, PHONONS 012010, S.T. Sound (or lattice vibration) can be described by a phonon just as light can be considered as photons, and therefore one can state that SASER is the acoustic analogue of the laser. Therefore, such kind of SASER is tunable (i.e. When a particle in the upper state interacts with a photon matching the energy separation of the levels, the particle may decay, emitting another photon with the same phase and frequency as the incident photon. This results to the assumption that the effective pump wave acting on the bubbles does not depend on the spatial coordinates. On the other hand, for devices such as SASERs, acoustic phonons have a considerable dispersion. In the proposed scheme, an application of an electrical bias to a semiconductor superlattice is increasing the amplitude of coherent folded phonons generated by an optical pulse. Sound amplification according to the experiment taken in the University of Nottingham could be based on an induced cascade of electrons in semiconductor superlattices. The solution of these equations gives that separately phonon and indirect exciton modes have no definite phase and only the sum of their phases is defined. However, optical phonons have a short life-time (they split into two due to anharmonicity) and therefore they add some important complications. One can mention that the stimulated emission is a procedure where we have a spontaneous and an induced emission at the same time. An example is a common sound amplification system with a microphone, amplifier and speaker. In contrast, the determination of the starting pressure in ordinary lasers is independent from the number of radiators. In coupled quantum wells there are two possible ways for electrons and holes to be bound into an exciton: indirect exciton and direct exciton. Together with the increase in amplitude, the spectrum of the bias-induced oscillations is narrower than the spectrum of the coherent phonons at zero bias. The saser mimics this technology, but using sound, to produce a sonic beam of phonons. Tens of thousands of stone circles in southern Africa form cymatic symbols. A SASER device transforms the electric potential energy in a single vibrational mode of the lattice (phonon).[10]. The evidence is starting to pile up, yet academics are avoiding these incredible findings. Electron states in quantum wells respond sensitively to moderate electric fields either by the quantum confined Stark effect in the case of wide barriers or by Wannier-Stark localization in the case of a superlattice. [31] Stokes wave refers to a non-linear and periodic surface wave on an inviscid fluid (ideal fluid assumed to have no viscosity) layer of constant mean depth. This energy was amplified by a simple understanding of harmonics and utilised in the same way that we generate LASER and SASER beam technology today. Viewed as Brillouin process, the system accesses a regime in which the phonon plays the role of Stokes wave. An essential statement here is that this proposed phonon laser can operate only if the temperature is much lower than the energy gap in the semiconductor. [citation needed], Instead of a feedback-built wave of electromagnetic radiation (i.e., a laser beam), a SASER delivers a sound wave. Basic understanding of the SASER development requires the evaluation of some proposed examples of SASER devices and SASER theoretical schemes. When the microphone is in front of the speaker, we hear an annoying whistle. They have built their device out of electrons moving through a series of structures known as quantum wells. Some methods for sound amplification of GHz-THz have been proposed so far. Above is a 2013 Ted Talk using resonance frequency to destroy cancer cells, saser technology similar to laser but uses targeted sound vibration. The bubble density in the liquid is initially distributed uniformly in space. According to a member of the Nottingham group, the two approaches are complementary and it should be possible to use one device or the other to create coherent phonons at any frequency in the megahertz to terahertz range. In general, every oscillator consists of three main parts. Also note: E2 > E1. Evidence that this ancient civilization was mining GOLD on a vast scale across all of southern Africa; They had knowledge of SASER technology, The stone circles were NOT dwellings for humans or animals but rather a giant ENERGY generating grid. The conversion between real space and k-space is a mathematical transformation called the Fourier transform and thus k-space can be also called Fourier space. On the other hand, in narrow-gap semiconductors this variation of energy is considerable and therefore external pressure or magnetic field may serve the purpose of tuning into the resonance of one-phonon interband transition. energy pattern" ... to predict the "hyperdimensional energy production/distribution" within a given planet/star. Both phonons and photons are bosons and thus, they obey Bose–Einstein statistics. https://www.facebook.com/rikalava12/videos/1221748494517494/, https://missiongalacticfreedom.wordpress.com/2014/02/10/teotihuacan-incredibly-resemble-a-modern-day-computer-circuit-board-of-todays/, http://www.ancient-origins.net/…/incredible-rust-resistant-…, stones used to construct Stonehenge hold musical properties, https://theeyeonscaredknowledge.wordpress.com/2016/05/21/megaliths-and-the-perfect-circle-of-sound/, http://ufosightingshotspot.blogspot.com/2014/11/michael-tellinger-on-evidence-of-300000.html, https://www.youtube.com/watch?v=tG16XyJuBNc, https://www.youtube.com/watch?v=p2bSvQxwcPQ, https://www.cymascope.com/cyma_research/biology.html, http://www.cymascope.com/iphoneweb/cymaphone/cyma_research/biology.html, http://www.spiritofmaat.com/archive/mar1/cymatics.htm, https://www.youtube.com/watch?v=05Io6lop3mk, https://www.youtube.com/watch?v=CpDgiyvNtaA, http://www.cymascope.com/cyma_research/musicology.html, http://projectavalon.net/forum4/showthread.php…, https://yngstls.wordpress.com/2014/02/06/music-notation-with-cymatics/, www.youtube.com/watch?v=Q3oItpVa9fs&feature=youtu.be, https://www.youtube.com/watch?v=Yimor2jRmCA&feature=youtu.be&t=9, https://www.gaia.com/video/lost-cities-beneath-ocean?fullplayer=feature, https://www.youtube.com/watch?v=0otLrDKV8uI, http://www.ancient-origins.net/ancient-places-americas/what-happened-sunken-city-cuba-001883, https://www.youtube.com/watch?v=1s1n5lRilXM, http://visupview.blogspot.com/2013/05/has-pyramid-been-discovered-beneath.html, https://www.youtube.com/watch?v=gYajkHqqqak, http://unearth.info/two-giant-underwater-crystal-pyramids-discovered-in-the-center-of-the-bermuda-triangle, www.youtube.com/watch?v=3xSWfa3sPkY&feature=youtu.be, http://www.nasa.gov/centers/goddard/universe/, http://science.nasa.gov/science-news/science-at-nasa/2003/09sep_blackholesounds/, http://www.ted.com/talks/evan_grant_cymatics.html, ttp://www.cymascope.com/cyma_research/physics.html, http://www.speakdolphin.com/ResearchItems.cfm?ID=6, http://undergroundhealthreporter.com/dna-science-and-reprograming-your-dna/#ixzz3NaflJYma, http://www.enterprisemission.com/china/Chinese%20Lunar%20Landing.htm, http://www.nbcnews.com/science/scientists-revive-sacred-sounds-6C10402460, http://www.independent.co.uk/news/science/nasa-puzzled-by-huge-8000-year-old-mystery-structures-in-kazakhstan-that-resemble-ancient-crop-a6717766.html, http://lairdscranton.com/laird-scranton-books/sacred-symbols-dogan-2007/, http://divinecosmos.com/start-here/davids-blog/1173-space-program-livestream, http://www.ancient-origins.net/news-history-archaeology/have-enormous-megaliths-been-discovered-southern-siberia-09912, http://www.infowars.com/newly-found-megalithic-ruins-in-russia-contain-the-largest-blocks-of-stone-ever-discovered/, http://nhmetaphysical.com/2014/07/newly-found-megalithic-ruins-in-russia-contain-the-largest-blocks-of-stone-ever-discovered/, https://www.youtube.com/watch?v=ARdAiJS97Ig, https://www.youtube.com/watch?v=sCN7eSsSbaU, http://www.theguardian.com/world/2015/apr/24/liquid-mercury-mexican-pyramid-teotihuacan, http://www.livescience.com/22454-ancient-chinese-tomb-terracotta-warriors.html, http://spherebeingalliance.com/blog/transcript-cosmic-disclosure-contact-is-made.html, https://books.google.com/booksid=Z9wCEzS2t64C&pg=PT327&lpg=PT327&dq=Brotherhood+of+the+bell+mercury&source=bl&ots=8jhOL-34N3&sig=UAtgMSOoEXpyvytCXFZYtqw8zws&hl=en&sa=X&ved=0, http://piramidasunca.ba/eng/latest-news/item/9788-science-proof-fence-resoundingly-breached-89-scientific-papers-delivered-at-five-international-scientific-conferences-on-the-bosnian-pyramids.html. The Pythagoras Cup (Pythagorean Cup) is the name given to a drinking cup attributed to the ancient Greek philosopher, Pythagoras of Samos. A fundamental characteristic of lasing, like the population inversion, is not actually possible in a two-level system and therefore a two level-laser is not possible. The problem stems from the fact that sound travels much slower than light. 67, 92−100(April 1997), "Sound laser could be the key to manipulating nanoparticles", "Electron-Phonon Effects on Transport in Mesoscopic Heterostructures", Sonic lasers--a shot heard 'round the world, "Phonon Laser Action in a Tunable Two-Level System", https://en.wikipedia.org/w/index.php?title=Sound_amplification_by_stimulated_emission_of_radiation&oldid=1013826270, Articles with dead external links from December 2019, Articles with unsourced statements from February 2016, Creative Commons Attribution-ShareAlike License, This page was last edited on 23 March 2021, at 17:25.
