On the emergence of quantum many-body chaos for tunably-broken integrability
Sounak Biswas, Sthitadhi Roy, Roderich Moessner
We develop a quantitative theory for the emergence of quantum many-body chaos as integrability is broken via a tunable parameter. In a circuit model of free fermions, 'doped' with…

How many-body chaos emerges in the presence of quasiparticles
Sibaram Ruidas, Sthitadhi Roy, Subhro Bhattacharjee +1
Many-body chaos is a default property of many-body systems; at the same time, near-integrable behaviour due to weakly interacting quasiparticles is ubiquitous throughout condensed…
