It’s been taking me forever to sort out and write down the details of implications of the proposal described here. While waiting for that to be done, I thought it might be a good idea to write up one ...

This past summer Nordita ran a program on quantum gravity, featuring lectures and panel discussions on various approaches to the subject. Lecture notes from the six mini-courses are now available here ...

String theory, conceptualized more than 50 years ago as a framework to explain the formation of matter, remains elusive as a “provable” phenomenon. But a team of physicists has now taken a significant ...

The seminar will have a special RTG talk at 4:00 P.M. every Thursday when the seminar meets. The RTG talk will be aimed at graduate students and post-docs; regular faculty are requested not to attend.

We will present a novel technique enabling us to prove that correlations of classical models of statistical physics decay exponentially fast in the subcritical regime. The strategy, relying on ...
