Thermal field theories : proceedings of the 2nd Workshop on Thermal Field Theories and Their Applications, Tsukuba, Japan, July 23-27, 1990 /
Theories of quantum fields at non-zero temperature have been steadily developed for well over a decade. In 1988, as a result of the increased demand for communication among theorists working in different fields ranging from condensed matter physics to high energy physics and astrophysics, the first...
