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.

Measurement and entanglement both have a “spooky” nonlocal flavor to them. Now physicists are harnessing that nonlocality to probe the spread of quantum information and control it.

Inside of a black hole, the two theoretical pillars of 20th-century physics appear to clash. Now a group of young physicists think they have resolved the conflict by appealing to the central pillar of the new century — the physics of quantum information.
