# Thermalization by a synthetic horizon

@inproceedings{Mertens2022ThermalizationBA, title={Thermalization by a synthetic horizon}, author={Lotte Mertens and Ali G. Moghaddam and Dmitry Chernyavsky and Corentin Morice and Jeroen van den Brink and Jasper van Wezel}, year={2022} }

Synthetic horizons in models for quantum matter provide an alternative route to explore fundamental questions of modern gravitational theory. Here, we apply these concepts to the problem of emergence of thermal quantum states in the presence of a horizon, by studying ground-state thermalization due to instantaneous horizon creation in a gravitational setting and its condensed matter analogue. By a sudden quench to position-dependent hopping amplitudes in a one-dimensional lattice model, we…
