Journey to the Center of a Black Hole
Vyshnav Mohan
An infalling two-point function of a scalar field in a three-dimensional BTZ black hole, with one operator inserted in the exterior and the other inserted along a timelike geodesic…
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 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…
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…
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…
State-independent Black Hole Interiors from the Crossed Product
Chethan Krishnan, Vyshnav Mohan
Opinion is divided about the nature of state dependence in the black hole interior. Some argue that it is a necessary feature, while others argue it is a bug. In this paper, we con…
Krylov Complexity of Open Quantum Systems: From Hard Spheres to Black Holes
Vyshnav Mohan
We examine the complexity of quasi-static chaotic open quantum systems. As a prototypical example, we analytically compute the Krylov complexity of a slowly leaking hard-sphere gas…
Interpreting the Bulk Page Curve: A Vestige of Locality on Holographic Screens
Chethan Krishnan, Vyshnav Mohan
Areas of extremal surfaces anchored to sub-regions on screens in Minkowski space satisfy various entanglement entropy inequalities. In 2+1 dimensions where the arguments are simple…
Hints of Gravitational Ergodicity: Berry's Ensemble and the Universality of the Semi-Classical Page Curve
Chethan Krishnan, Vyshnav Mohan
Recent developments on black holes have shown that a unitarity-compatible Page curve can be obtained from an ensemble-averaged semi-classical approximation. In this paper, we empha…
Machine Learning Gauged Supergravity
Chethan Krishnan, Vyshnav Mohan, Soham Ray
Type IIB string theory on a 5-sphere gives rise to gauged supergravity in five dimensions. Motivated by the fact that this is the context of the most widely stu…
Quantum interactions, Predictability and Emergence Of Gravity
Vyshnav Mohan
In this paper, we will show that gravity can emerge from an effective field theory, obtained by tracing out the fermionic system from an interacting quantum field theory, when we i…
Back-reaction of quantum processes and modified gravitational dynamics
Vyshnav Mohan
In this paper, we seek to find a modified theory of gravity that accounts for the back-reaction of QED on curved spacetime. It is already known that vacuum fluctuations induce inte…
