Tidal heating of Quantum Black Holes and their imprints on gravitational waves

Abstract

The characteristic difference between a black hole and other exotic compact objects (ECOs) is the presence of the horizon. The horizon of a classical black hole acts as a one-way membrane. Due to this nature, any perturbation on the black hole must satisfy ingoing boundary conditions at the horizon. For an ECO either the horizon is replaced or modified with a surface with non zero reflectivity. This results in a modification of the boundary condition of the perturbation around such systems. In this work, we study how tidal heating of an ECO gets modified due to the presence of a reflective surface and what implication it brings for the gravitational wave observations. We also argue that the position of the reflective surface, $\epsilon$ $\gtrsim \mathcal{O}(10^{-5})$, can have an observational impact in extreme mass ratio inspirals.
