High Energy Theory
The research effort of the high energy theory group covers a wide range
of fields, including general quantum field theory, string theory, quantum
gravity models in various dimensions, the theory of turbulence, particle
cosmology, and also computer simulations of problems that arise in these
areas.
The activity in string theory and quantum gravity is aimed at
developing a quantum theory that incorporates the physics of gravity
and is valid down to the smallest length scales, where conventional quantum
field theory can no longer be applied. There has been rapid progress in
this area in recent years, in part due to work of Princeton faculty and
students, and it continues to be a fertile source of research problems.
Black hole theory provides an important testing ground for the quantum
theory of gravity and in recent work significant progress has been achieved
in explaining black hole entropy and Hawking radiation from a more
fundamental point of view.
Work on quantum black holes has lead to new relations between
strings and nonAbelian gauge theory. This application of string
theory has already provided new insights into strongly coupled
gauge theories, and it continues to be an exciting area.
Members of the high energy theory group are also involved in
crossdisciplinary research, applying field theoretic techniques to a
variety of problems, including turbulent flow, dissipative quantum systems,
and the quantum Hall effect, to name a few.
