Citation | Distinguished for many papers in statistical physics covering a wide range of topics. His early research was on the application of scaling theories to spin lattices and to superfluidity, and contained a series of power results on critical indices. He then applied renormalization group ideas to polymer solutions and clarified the relationship of this approach to previous theories; a particularly interesting result concerned the retrieval of the Flory index under approximation schemes. After some good work on criticality on surfaces, he joined the (then) new spin glass field, and in collaboration with A.S. Bray wrote a series of important papers both on the analytic structure of these systems, and on the properties revealed by computer simulation, a series still continuing. He is a theoretical physicist of notable analytic power, producing work of the highest quality. |
