Carrollian holographic duals are non-local
Jordan Cotler, Prateksh Dhivakar, Kristan Jensen
Mapping the -matrix of a generic theory of flat space gravity coupled to matter to correlation functions of a putative Carrollian dual, we show that bulk interactions imply boun…
Quantum Probe Tomography
Sitan Chen, Jordan Cotler, Hsin-Yuan Huang
Characterizing quantum many-body systems is a fundamental problem across physics, chemistry, and materials science. While significant progress has been made, many existing Hamilton…
An Egorov Theorem for Wasserstein Distances
Jordan Cotler, Felipe Hernández
We prove a new version of Egorov's theorem formulated in the Schrödinger picture of quantum mechanics, using the -Wasserstein metric applied to the Husimi functions of quantum…
Norm of the no-boundary state
Jordan Cotler, Kristan Jensen
We consider Einstein gravity with positive cosmological constant coupled to matter in an asymptotically de Sitter universe with sphere boundary at timelike infinity. In this settin…
Emergent unitarity in de Sitter from matrix integrals
Jordan Cotler, Kristan Jensen
We study Jackiw-Teitelboim gravity with positive cosmological constant as a model for de Sitter quantum gravity. We focus on the quantum mechanics of the model at past and future i…
Low-dimensional de Sitter quantum gravity
Jordan Cotler, Kristan Jensen, Alexander Maloney
We study aspects of Jackiw-Teitelboim (JT) quantum gravity in two-dimensional nearly de Sitter (dS) spacetime, as well as pure de Sitter quantum gravity in three dimensions. These…
