Dynamical Black Hole Emission
David A. Lowe, Larus Thorlacius
Semiclassical black hole emission in four spacetime dimensions is studied using a non-local effective action. The field equations that determine the time-dependent renormalized str…
Generalized Effective Field Theory for Four-Dimensional Black Hole Evaporation
Bing-Nan Liu, David A. Lowe, Larus Thorlacius
The quantum induced stress tensor of 3+1-dimensional Einstein gravity, with conformally coupled matter, is studied in an effective field theory approach. In this context, Riegert's…
Black Shell Thermodynamics
Ulf Danielsson, Vyshnav Mohan, Larus Thorlacius
Black shells have been proposed as black hole mimickers, i.e. horizonless ultra-compact objects that replace black holes. In this paper, we assume the existence of black shells and…
Late-Time Saturation of Black Hole Complexity
Friðrik Freyr Gautason, Vyshnav Mohan, Lárus Thorlacius
The holographic complexity of a static spherically symmetric black hole, defined as the volume of an extremal surface, grows linearly with time at late times in general relativity.…
Non-Perturbative Corrections to Charged Black Hole Evaporation
Vyshnav Mohan, Lárus Thorlacius
The recent work of Brown et al. (arXiv:2411.03447) demonstrated that the low-temperature evaporation rate of a large near-extremal charged black hole is significantly reduced from…
