Donald Spector, professor of physics, spent most of the past summer in Japan as a Fellow of the Japan Society for the Promotion of Science (JSPS). Spector was selected in a two-stage process, first requiring nomination by the U.S. National Science Foundation, and then selection by the JSPS.
As a JSPS Fellow, Spector conducted research in theoretical physics at some of Japan's leading scientific institutions. Spector was in residence at Kyoto University, where he split his time between the Physics Department and the Yukawa Institute for Theoretical Physics; at RIKEN, also known as the Institute for Physical and Chemical Research, outside Tokyo; and at KEK, the High Energy Physics Laboratory of Japan, in Tsukuba.
In addition to working with scientists at these various institutes, Spector gave seminars on his research in supersymmetric physics at all three locations. In his research this summer, Spector addressed issues associated with central charges in supersymmetric theories, generalized his previous work on partial supersymmetry to explain the spectral equivalence of some distinct differential operators, and demonstrated the existence of shape invariance in a class of string-related models.
