Itzhak Bars (born 31 August 1943, İzmir, Turkey) is a theoretical physicist at the University of Southern California in Los Angeles.
from Robert College in physics in 1967, Bars obtained his Ph.D. under the supervision of Feza Gürsey at Yale University in 1971.
Some of his experimentally successful physics predictions include supersymmetry in large nuclei with even/odd numbers of nucleons, and the weak interaction contribution to the anomalous magnetic moment of the muon, in the context of the quantized Standard Model, which was confirmed after 30 years.
To explain to the layman how this gauge symmetry works, Bars makes an analogy between the phenomena in the 4+2 dimensional world and events happening in a hypothetical 3-dimensional room.
In this analogy, the two-dimensional surfaces that make up the boundaries of the three-dimensional room (walls, ceiling, floor) are the counterparts of the 3+1 dimensional world humans live in as observers.
Itzhak Bars's current interests include String Field Theory, 2T-Physics which he originated in 1998, Cosmology and Black Holes and Particle Physics at accelerators.
An important prediction of this approach is that the Standard Model coupled to General Relativity must be invariant under local scaling transformations in 3+1 dimensions.
This local Weyl symmetry in turn provides new tools to investigate new features of 3+1 dimensional space-time in the very early cosmological history of the universe and in the interior of black holes.
