Quantum structures of black holes KU Leuven
Black holes are the inevitable endpoints of gravitational collapse of matter with sufficient mass. They are ubiquitous in our own Universe.
Hawking famously showed that black holes carry entropy proportional to their horizon area, meaning that they hold a large number of microscopic states. To do so, he relied on a semi-classical approximation, where he assumed that quantum fields fluctuate around a fixed classical black hole background. ...
