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 manybody 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 upspin 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.
