Mario Rabinowitz (born October 24, 1936) is an American physicist who has published 170 scientific papers on a wide variety of subjects such as black holes, superconductivity, classical tunneling, the nuclear electromagnetic pulse, the equivalence principle, physical electronics, electrical discharges, surface physics, and vacuum physics. He has written four articles for the Encyclopedia of Science and Technology: Two are feature articles on Advanced Electric Power Transmission, and on the Nuclear Electromagnetic Pulse, in the 1981 and 1986 Yearbooks respectively. Two others are articles on Electrical Insulation (1982, 1987,1992, 1997, and 2002), and Superconducting Devices (1989). He wrote Chapters in three astrophysics books. One Chapter is "Black Hole Paradoxes" http://arxiv.org/abs/astro-ph/0412101.
He was on the Editorial Board of the IEEE Transactions on Applied Superconductivity for many years. His publications are in journals such as Physical Review Letters, Physical Review, International Journal of Theoretical Physics, Concepts of Physics, Applied Physics Letters, Journal of Applied Physics, Nuclear Physics, Physica, Astrophysics and Space Science, Chemical Physics Letters, Modern Physics Letters, International Journal of Modern Physics, Foundations of Physics, etc. He has over 50 patents.
Rabinowitz received B.S. and M.S. degrees in Physics in 1959 and 1960 at the University of Washington. He was a Baker Scholar at Reed College. He was awarded the PhD. degree in Physics by Washington State University in 1963.
Rabinowitz has been CEO of Armor Research since 1995. He was Senior Scientist at the Electric Power Research Institute (EPRI) from 1974 to 1995. Prior to joining EPRI, he did research at Stanford University's SLAC for 7 years. Previously, he was a Manager at Varian Associates, and a Senior Physicist at the Westinghouse Research Center. He has been an Adjunct Professor at Georgia Institute of Technology, Univ. of Houston, Virginia Commonwealth Univ., Case-Western Univ., and Boston Univ. He has also taught at Stanford Univ. and San Jose State Univ. He received the 1992 Washington State Univ. Alumni Achievement Award.
Black-hole radiation
Rabinowitz was the first to show that the complicated Stephen Hawking equation for Black Hole Radiation can be reduced to a linear equation with only one parameter, the black hole density ', yielding the simplest possible equation . He also derived the power radiated from a black hole by Gravitational Tunneling Radiation. http://arxiv.org/abs/physics/0506029 and http://arxiv.org/abs/physics/0503079.
High-Q superconducting cavity breakdown
Rabinowitz was the first to develop a theory that predicts why the Q ~ 1011 of a superconducting cavity, drops precipitously at a magnetic breakdown field, well below the critical field of the superconductor. He showed that the power dissipation from at least one oscillating fluxoid accounts for the steep drop in cavity Q. The fluxoid is trapped in either a type I or type II superconductor due to an incomplete Meissner-Ochsenfeld effect as the superconductor is cooled below its transition temperature. http://arxiv.org/abs/cond-mat/0306202
Flux trapping in a superconductor in violation of the Meissner effect
Following his insightful fluxoid trapping model to account for losses in superconducting cavities, Rabinowitz together with his colleagues succeeded in purposely trapping large permanent magnetic fields (with high fidelity to the original field) transversely to the axes of hollow superconducting cylinders. This is a virtual violation of the Meissner Effect, and it was quickly confirmed, and stable magnetic fields in excess of 100,000 Oersteds have since been successfully trapped. http://arxiv.org/abs/cond-mat/0308363
General equation for superfluids and wide range of superconductors
Rabinowitz derived a basic and inherently simple equation which agrees well with the superconducting transition temperatures for the heavy-electron, cuprate, oxide, organic, and metallic superconductors, metallic hydrogen, and neutron stars; and also works well for the superfluid transition temperature of 2.6 mK for liquid 3He. Reasonable estimates are made from 10-3 K to 109 K -- a range of 12 orders of magnitude. http://arxiv.org/abs/cond-mat/0304173
Exaggerated effects of nuclear electromagnetic pulse
Rabinowitz was the first to show that the claim that one high-altitude nuclear burst could black out the entire USA was an exaggeration that violates conservation of energy. This negated the strategy of immediate massive retaliation upon the detection of a single incoming warhead, as a large segment of the USA would be unaffected. Thus a rogue power could not instigate a nuclear war between the USA and the USSR. Rabinowitz furthermore showed that multiple concurrent nuclear bursts would not have an additive effect, but would interfere to produce less EMP than a single burst because the ionization produced by each burst severely attenuates the EMP that the others can produce. http://arxiv.org/abs/physics/0307127
The equivalence principle classically and quantum mechanically
Rabinowitz has pointed out that despite the outstanding success of Einstein's General Relativity (EGR), there may be exceptions to the Equivalence Principle which is the very cornerstone upon which EGR is based. He considered a gedanken experiment with three spherically symmetric masses in a straight line with mass M (e.g. the earth) an equal distance between m2 and m1 with M >> m2 > m1, and equal radii for m2 and m1. When let go, the three bodies accelerate toward their common center of mass (C-M). Since the center of mass of the system is between the centers of M and m2, m2 will have a shorter distance to fall toward the C-M; and ml will have a longer distance to fall than m2 to reach the C-M. All three bodies must reach the C-M at the same instant because the C-M cannot move in the absence of an external force. Since the lightest mass ml has to go the farthest distance to reach the C-M, it must go the fastest relative to the C-M. [The same conclusion holds if the masses are not collinear; and also for two masses.] This appears to violate the Weak Equivalence Principle and hence the Strong Equivalence Principle in Classical Mechanics; and Rabinowitz has shown that these are violated in Quantum Mechanics. Such considerations may need to be incorporated to create a successful theory of Quantum Gravity. http://arxiv.org/abs/astro-ph/0701358 and http://arxiv.org/abs/physics/0608193
Internal inconsistencies in quantum mechanics
Rabinowitz found discrepancies and accords between quantum (QM) and classical mechanics (CM) related to expectation values and periods for both the simple harmonic oscillator (SHO) and a free particle in a box (FPB), which may apply generally. These indicate non-locality is expected throughout QM. The FPB energy states violate the Correspondence Principle. Previously unexpected accords are found for the expectation values of X2 and beat periods for the SHO for all quantum numbers, n. http://arxiv.org/abs/0804.3373
Classical tunneling
Cohn and Rabinowitz were the first to show that a classical representation of an extended body over barriers of height greater than the energy of the incident body is shown to have many features in common with quantum tunneling as the center-of-mass literally goes through the barrier. They showed that a distribution of body lengths around the de Broglie wavelength leads to reasonable agreement with the quantum transmission coefficient.
