Energy trapping from Hagedorn densities of states
Connor Behan, Klaus Larjo, Nima Lashkari +2
In this note, we construct simple stochastic toy models for holographic gauge theories in which distributions of energy on a collection of sites evolve by a master equation with so…
Loop effects and infrared divergences in slow-roll inflation
Klaus Larjo, David A. Lowe
Loop corrections to observables in slow-roll inflation are found to diverge no worse than powers of the log of the scale factor, extending Weinberg's theorem to quasi-single field…
Black holes without firewalls
Klaus Larjo, David A. Lowe, Larus Thorlacius
The postulates of black hole complementarity do not imply a firewall for infalling observers at a black hole horizon. The dynamics of the stretched horizon, that scrambles and re-e…
Initial states and infrared physics in locally de Sitter spacetime
Klaus Larjo, David A. Lowe
The long wavelength physics in a de Sitter region depends on the initial quantum state. While such long wavelength physics is under control for massive fields near the Hartle-Hawki…
Black Holes as Rubik's Cubes
Bartłomiej Czech, Klaus Larjo, Moshe Rozali
We propose a unitary toy model of black hole evaporation, in which the entanglement between the interior and exterior degrees of freedom vanishes at late times. Our model possesses…
Vacuum decay in multidimensional field landscapes: thin, thick and intersecting walls
Vijay Balasubramanian, Bartlomiej Czech, Klaus Larjo +1
We study tunneling between vacua in multi-dimensional field spaces. Working in the strict thin wall approximation, we find that the conventional instantons for false vacuum decay d…
