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…
Breakdown of Semiclassical Gravity in Four-Dimensional Black Hole Evaporation
David A. Lowe, Larus Thorlacius
We study black hole formation and evaporation in a four-dimensional semiclassical model that preserves diffeomorphism invariance and reproduces the one-loop trace anomaly. Solving…
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…
Carroll Strings with an Extended Symmetry Algebra
Matthias Harksen, Diego Hidalgo, Watse Sybesma +1
Starting from the Polyakov action we consider two distinct Carroll limits in target space, keeping the string worldsheet relativistic. The resulting magnetic and chiral Carroll str…
Holographic models with anisotropic scaling
E. J. Brynjolfsson, U. H. Danielsson, L. Thorlacius +1
We consider gravity duals to d+1 dimensional quantum critical points with anisotropic scaling. The primary motivation comes from strongly correlated electron systems in condensed m…
AdS/CFT and the Information Paradox
D. A. Lowe, L. Thorlacius
The information paradox in the quantum evolution of black holes is studied within the framework of the AdS/CFT correspondence. The unitarity of the CFT strongly suggests that all i…
Hot String Soup
D. A. Lowe, L. Thorlacius
Above the Hagedorn energy density closed fundamental strings form a long string phase. The dynamics of weakly interacting long strings is described by a simple Boltzmann equation w…
String Thermalization at a Black Hole Horizon
A. Mezhlumian, A. Peet, L. Thorlacius
Susskind has recently shown that a relativistic string approaching the event horizon of a black hole spreads in both the transverse and longitudinal directions in the reference fra…
