Black holes are one of the most fascinating predictions of Einstein’s general relativity. With a high-resolution image of a supermassive black hole at the center of M87 by the Event Horizon Telescope and recent gravitational wave observations of binary black hole collisions by LIGO at hand, there are no longer any doubts that black holes exist in our Universe. However, the very existence of black holes still raises many fundamental theoretical questions. Those related to quantum processes, such as the mystery of black hole entropy, information loss, quantum evaporation and black hole thermodynamics, are expected to provide key insights towards understanding how to reconcile gravity with quantum theory. Other are purely classical and range from describing astrophysical processes to pure mathematical physics.

In this project we are going to investigate certain aspects of black hole physics, the specific topic being determined by the taste of the student and recent developments in the field. This may include my current interests (see https://inspirehep.net), such as the “black hole chemistry” and its holographic interpretation, probing the quantum information aspects of spacetimes with the Unruh-De Witt detector, or purely classical investigations of separability of various test field equations in black hole backgrounds employing hidden symmetries. I am also very open to novel ideas and directions.
