Quantum nucleation of black hole mimickers via chaos dominated tunneling
Ulf Danielsson, Suvendu Giri, Vyshnav Mohan +1
Black hole mimickers, ultracompact horizonless objects, have been proposed as alternatives to black holes in a variety of settings, including extensions of general relativity and s…
Spacetime from Operator Algebras
Vyshnav Mohan, Larus Thorlacius
Under suitable assumptions, geometric objects such as the spacetime metric and curvature tensor can be reconstructed from the algebra of operators of quantized matter fields in the…
De Sitter Complexity Grows Linearly in the Static Patch
Vyshnav Mohan, Watse Sybesma
The observable universe has undergone periods of expansion that are well approximated by de Sitter (dS) space. Still lacking is a quantum mechanical description of dS, both globall…
Black Hole Singularities from Holographic Complexity
Vyshnav Mohan
Using a second law of complexity, we prove a black hole singularity theorem. By introducing the notion of trapped extremal surfaces, we show that their existence implies null geode…
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.…
