Presidential Young Investigator Award: Research on String and Conformal Field Theories

点击翻译按钮获取中文摘要

Research will continue in string theory, studying solutions already discovered to string vacua to get some insight into the fundamentals of strings. Also, since string theory appears to be a consistent theory of quantum gravity, it is planned to use it to address such questions as the high temperature regime in thermodynamics, high energy limits of scattering amplitudes, singularities of the standard cosmology, and singularities of black holes. Particular topics include an attempt to find solutions of string equations which do not have "time" in the usual sense and an effort to understand how string theory modifies the standard cosmological scenario, and how strings can predict the dimensionality of space-time.
