Emergence of Krylov complexity through quantum walks: An exploration of the quantum origins of complexity
Dimitrios Patramanis, Watse Sybesma
The paper links quantum random walks on graphs to Krylov (spread) complexity, deriving analytic Lanczos coefficients for the SYK model and characterizing Krylov complexity of hyper…
Limits on the Statistical Description of Charged de Sitter Black Holes
Lars Aalsma, Puxin Lin, Jan Pieter van der Schaar +2
The thermodynamics of de Sitter black holes is complicated by the presence of two horizons and the absence of a globally defined timelike Killing vector. The standard choice of the…
Quantum Fluctuations and Newton-Cartan Geometry for Non-Relativistic de Sitter space
Matthias Harksen, Diego Hidalgo, Watse Sybesma
We study a non-relativistic realisation of two-dimensional de Sitter gravity both from its boundary and bulk description with the goal of learning about de Sitter space and paving…
New Rotating Black Holes in String Theory
Watse Sybesma, Poula Tadros
We present new black hole solutions to the low-energy effective action of string theory. We introduce three- and four-dimensional solutions that are rotating, asymptotically flat,…
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…
The spectrum of a quantum Lifshitz black hole in two dimensions
Matthias Harksen, Watse Sybesma
We examine the low-energy spectrum of a four-dimensional near-extremal black hole that arises as a solution to a low energy effective theory of heterotic string theory. The effecti…
