Our research includes a strong focus on fundamental questions about the new physics underlying the Standard Models of particle physics, cosmology, and gravity; and the nature and applications of our basic frameworks (quantum field theory and string theory) for attacking these questions. Our research also includes a major emphasis on the novel phenomena in condensed matter physics that emerge in systems with many degrees of freedom.
To most physicists, almost everything about evolution is puzzling. What determines how much complexity can — and has — evolved?
String theory has enjoyed tremendously fruitful interactions with modern mathematics. Some of the simplest and most interesting questions in number theory and geometry involve counting (for instance, determining numbers of integer solutions to certain equations).
