Prof. Lawrence Horwitz has continued studies of a consistent classical and quantum theory in the framework of special relativity. It has resulted in a new proof of a theorem used to find the ground state energy of a many-body system and a new stability analysis in statistical mechanics. He has studied a recent experiment showing interference in time and explained the results in terms of this theory. The theory for a proposed experiment which should demonstrate entanglement of correlated spins (such as spin up-spin down combinations to form spin zero) separated in time was also worked out by Horwitz using the formulation of spin in this theory, resulting in a prediction that could be verified in experiment. He has recently embedded the theory into general relativity as a complete classical and quantum theory, and applications have been worked out, such as dynamical effects in the neighborhood of a black hole horizon, scattering and gauge theory forming a basis for the recent development of an approach to modified Newtonian law behavior of galaxies with anomalous rotation curves. Another topic in his interest has been that of unstable systems. A known theory developed for the description of resonances in classical wave systems was generalized to be applicable to quantum systems. In this form, he developed a theory in which resonances can be represented by actual states in the quantum Hilbert space, providing, for example, a basis for the applicability of particle sum rules. Finally, a new approach to standard Hamiltonian dynamics, embedding it into geometrical form was formulated, making available a criterion for stability based on the local deviation of orbits.
