The role of cutting edge research is to continuously bridge the gap between theoretical ideas and the real world. Recent experiments show that quantum physics applies to even biological cells which are the size of planets compared to electrons. As physicists continue to unveil the underlying secrets of how these widespread phenomena occur, the potential applications are limitless: acoustics, biology, teleportation, health, architecture, and many more. Recent experiments in quantum physics show that behavior which was previously limited to sub-atomic particles is actually widely applicable in other areas. For instance, several areas of biology such as smell, photosynthesis and bird migration are now proven to be governed by the rules of quantum physics. (see references below) This gives us a better understanding that if quantum physics can effect such complex and large things as biological cells, it can also effect smaller, simpler molecules such as air which are somewhere between the size of an electron and a biological cell.
The concept of Quantum Physics is that electrons can behave as waves, as individual particles or as both at the same time. ZR Acoustics creates the proper environment to control the behavior of Air molecules, forcing them to change from wave fashion to individual particle fashion. When Air molecules behave as individual particles (i.e. no wave behavior), sound energy has no medium to ride upon. Like a radio signal without a carrier wave, the sound simply ceases to exist. In conjunction with precise designs, this effect dramatically increases Phase Coherence, consequently improving both imaging and spaciousness.

Dr. Woon Siong Gan obtained his PhD at the age of 24. He completed his B.Sc. in Physics in 1965, his DIC in acoustics & vibration science in May 1967, and his Ph.D. in acoustics in February 1969, all from the Physics Department of the Imperial College London.His PhD thesis pioneered topological phase transition. IN 1966 he coined and invented the name transport theory in condensed matter physics. His PhD thesis also played a role in the founding of the field of condensed matter physics. Today transport theory is the foundation of theoretical design of materials. It is also an important theory in condensed matter physics and is related to phase transition.From 1970 to 1979, he was an associate professor at the Physics Department of Nanyang University in Singapore. From 1979 to 1989, he was a practicing acoustical consultant. In 1989, he founded Acoustical Technologies Singapore Pte Ltd, a research & technologies company engaging in ultrasound technologies, especially acoustical imaging. The company has since developed and patented the scanning acoustic microscope (SAM) and the surface acoustic wave (SAW) devices. Besides research and development works, he is also involved in fundamental research on transport theory approach to phase transition and phase transition as a transport phenomenon.He has published several papers on acoustical imaging,and the applications of gauge theory to acoustics.He is also the author of the books Acoustical Imaging: Techniques and Applications for Engineers.,published by John Wiley & Sons, New Acoustics,based on Metamaterials,published by Springer, Gauge Invariance Approach to Acoustic Fields, published by Springer, Signal Processing and Image Processing applied to Acoustical Imaging, published by Springer, Time Reversal Acoustics, published by Springer, and Nonlinear Acoustical Imaging published by Springer.
Applications of quantum physics are life-changing. Quantum physics can offer profound shifts to numerous global sectors. Computers and smartphones, lasers and telecommunications, atomic clocks and GPS and medical imaging such as MRI are all dependent on quantum physics to operate.
The full potential of quantum has yet to be realized. However, whilst scientists have been making huge steps forward in their understanding of it and are growing their abilities in harnessing its powers to build revolutionary systems, they are still struggling to apply quantum to mechanical systems. A large portion of modern technology uses systems with moving parts, mechanical systems, but up until recently, scientists have struggled to successfully incorporate quantum into these systems.
A breakthrough was made at the Institute for Molecular Engineering at the University of Chicago and Argonne National Laboratory, where scientists successfully connected quantum circuits to acoustic waves. The team built a mechanical system that can control sound waves at the quantum level. The system, essentially a tiny echo chamber, connects sound waves to quantum circuits in order to control them. The impact of this advancement is huge because for the first time a quantum system has been successfully intertwined with a mechanical one.
The accomplishment that the team has made is a big step beyond anything that has been achieved before. Experts see that successfully having the two technologies communicating with each other opens the door to numerous quantum applications, some of which we know about and others that will be discovered.
One application, in particular, that is shrouded in much interest in using this integration between quantum and mechanical systems to devise precise quantum sensors that would have capabilities far beyond sensors that are currently available. With quantum, sensors would have the ability to detect even the tiniest of vibrations and they would be capable of communicating with individual atoms.
The sense of force or displacement is the cornerstone of many modern sensors. Mechanical systems are the easiest to build in order to measure these kinds of movements, and with the added power of quantum, the capabilities of these sensors would explode.
What has been achieved at the University of Chicago and Argonne offers a way to create ultra-sensitive sensors. The research focused in part on investigating linking quantum electrical circuits to devices that generate surface acoustic waves, tiny sound waves that travel along the surface of a material and play essential roles in devices such as phones, radio receivers, and garage door openers. The team built the two systems separately and connected them together, meaning that each component was optimized but could also talk with the other. To function properly, the temperature of both systems were kept just a fraction above absolute zero.
In the near future, we could see the development of highly sensitive sensors that rely on this innovation that applies quantum to mechanical systems through quantum sound waves. We would see sensors based on quantum sound waves that can measure all manner of factors, such as those that we currently rely on light for. Much more investigation is needed in this area, however, it is without a doubt that this innovation will help to create better sensors in the future.
The new optical lattice findings could allow for more in-depth study of the physics of elasticity in quantum solids, as well as the creation of quantum neural networks. Referring to phonons, Lev notes that up until now, we couldn't study anything built upon that with quantum simulators employing atoms and photons because we couldn't emulate this basic form of sound.\"
GaN is a pivotal material for acoustic transducers and acoustic spectroscopy in the THz regime, but its THz phonon properties have not been experimentally and comprehensively studied. In this report, we demonstrate how to use double quantum wells as a THz acoustic transducer for measuring generated acoustic phonons and deriving a broadband acoustic spectrum with continuous frequencies. We experimentally investigated the sub-THz frequency dependence of acoustic attenuation (i.e., phonon mean-free paths) in GaN, in addition to its physical origins such as anharmonic scattering, defect scattering, and boundary scattering. A new upper limit of attenuation caused by anharmonic scattering, which is lower than previously reported values, was obtained. Our results should be noteworthy for THz acoustic spectroscopy and for gaining a fundamental understanding of heat conduction.
When a single quantum well (QW) is used as an acoustic transducer24,26,27,28, an acoustic signal initiated in the single QW is completely overwhelmed by strong transient electronic signals near zero time delay. However, it is necessary to measure the acoustic signals from a transducer in numerous cases of acoustic analysis. For multiple QWs2,14,15,18,19,20,22,23,25,29,30,31,32, the frequency components are limited because of the spatial period of the QWs, although obtaining approximations of the generation signals is feasible. Therefore, the frequency dependence of phonon MFPs in the sub-THz regime has not been experimentally and comprehensively investigated, despite the importance of the THz phonon properties of acoustic transducers.
The JBL Quantum 800 has acceptable imaging. The weighted group delay has a little bump in the low bass range, but otherwise, everything is below the audibility threshold, ensuring mostly tight bass and transparent treble reproduction. The L/R drivers of our test unit are fairly well-matched in amplitude and frequency response as well. However, there's a large phase mismatch between the L/R drivers of our test unit, and while it isn't very noticeable with real-life content, it could have a small negative effect on the stereo image and how objects are oriented spatially. That being said, these results are only valid for our unit, and yours may perform differently. 59ce067264
