Fundamentals of Quantum Physics

Exact determination of the eigenvalue spectrum of the quantum rotator in arbitrarily strong electric, magnetic, and vector potential fields. The quantum rotator is a model system for a wide range of physical phenomena. More Than One Mystery

Theory of composite quantum systems comprising charged particles and magnetic flux tubes. Such systems display novel quantum interference and quantum statistical effects and play a significant role in various low-temperature processes in condensed matter. More Than One Mystery

Theoretical description of new classes of quantum interference experiments involving the interference of entangled states and second order correlations of particles subjected to external potentials. Examples include hybrid experimental configurations combining the attributes of the Hanbury Brown-Twiss effect, Einstein-Podolsky-Rosen effect, and Aharonov-Bohm effect. Group theoretical analysis of particle interferometers led to the theoretical prediction of new types of multi-fermion states with surprising statistical properties.More Than One Mystery

Proposal of Ion Interferometry and test of the Aharonov-Bohm effect with ions. Ion interferometry gives rise to quantum interference effects sensitive not only to particle charge, but to internal electronic structure as well.More Than One Mystery

Investigation of new directions in electron microscopy and interferometry based on field-emission sources of atomic size. Such sources, used in the configuration of a point-projection microscope, produce a strongly focussed, highly coherent electron beam ideal for low-energy, lensless holographic imaging. The configuration provides detailed information about the coherence, brightness, and degeneracy of the source, and may serve as a basis for realising some of the new types of quantum interference effects in the preceding item.

Experimental tests of the proposition that radioactive nuclei disintegrate randomly, uninfluenced by the present state or past history of the nuclei. Tests of quantum processes for randomness have significant implications for the foundations of quantum mechanics as well as for practical matters involving quantum computation. The work introduced into physics powerful statistical procedures for assessing the randomness of physical processes. A Universe Of Atoms
