Imprint of the black hole singularity on thermal two-point functions
Nima Afkhami-Jeddi, Simon Caron-Huot, Joydeep Chakravarty +1
We consider two-point functions of light fields at finite temperature and large real frequencies in holographic theories. The thermal system is dual to a single-sided AdS black hol…
BBP Phase Transition for an Extensive Number of Outliers
Niklas Forner, Alexander Maloney, Bernd Rosenow
Random-matrix theory helps disentangle signal from noise in large data sets. We analyze rectangular matrices in which the noise generates a Marchenko…
The Optimal Rate Function in Covariant Quantum State Tomography
Arick Grootveld, Alexander Maloney, Jason Pollack +1
The problem of quantum tomography is to estimate an unknown quantum state from a measurement of copies of . One can ask which tomography protocol, i.e.\ which choice o…
A measure on the space of CFTs and pure 3D gravity
Alexandre Belin, Alexander Maloney, Florian Seefeld
We define a normalizable measure on the space of two-dimensional conformal field theories, which we interpret as a maximum ignorance ensemble. We test whether pure quantum gravity…
Lindblad evolution as gradient flow
Greg Kaplanek, Alexander Maloney, Jason Pollack +1
We give a simple argument that, for a large class of jump operators, the Lindblad evolution can be written as a gradient flow in the space of density operators acting on a Hilbert…
The spectrum of pure dS gravity in the static patch
Joydeep Chakravarty, Alexander Maloney, Keivan Namjou +1
We consider the quantum mechanical description of the de Sitter static patch in three-dimensional general relativity. We consider a Lorentzian path integral that conjecturally comp…
