Open system probes of renormalization group flow
Andrew Keefe, Brenden Bowen, Saptarshi Biswas +3
Open system probes can provide an efficient means to characterize quantum many-body systems by employing them as engineered environments. The key idea is to map long-range spatial…
Mutual information as a measure of renormalizability
Brenden Bowen, Albert Farah, Spasen Chaykov +1
Renormalization is an essential technique in field-theoretic descriptions of natural phenomena, where the absence of a UV-complete description yields an abundance of divergent quan…
Open system dynamics in interacting quantum field theories
Brenden Bowen, Nishant Agarwal, Archana Kamal
A quantum system that interacts with an environment generally undergoes nonunitary evolution described by a non-Markovian or Markovian master equation. In this paper, we construct…
Thermalization and localization in a discretized quantum field theory
Spasen Chaykov, Brenden Bowen, Nishant Agarwal
Localization marks the breakdown of thermalization in subregions of quantum many-body systems in the presence of sufficiently large disorder. In this paper, we use numerical techni…
