Models of Quantum Gravity and Edge States Ghent University
Understanding quantum gravity is one of the most fundamental problems in high-energy theoretical physics. We attack this problem using two a priori disjoint approaches.
The first consists of looking at classical gravity supplemented with quantum fields (or strings). It turns out the black hole horizon contains additional edge degrees of freedom squeezed to the horizon. These are related to Strominger's asymptotic soft gravitons, ...
