Information scrambling at finite temperature in local quantum systems
Subhayan Sahu, Brian Swingle
This paper investigates the temperature dependence of quantum information scrambling in local systems with an energy gap, , above the ground state. We study the speed and shape…

Many Body Localization Due to Correlated Disorder in Fock Space
Soumi Ghosh, Atithi Acharya, Subhayan Sahu +1
In presence of strong enough disorder one dimensional systems of interacting spinless fermions at non-zero filling factor are known to be in a many body localized phase. When repre…

Scrambling dynamics across a thermalization-localization quantum phase transition
Subhayan Sahu, Shenglong Xu, Brian Swingle
We study quantum information scrambling, specifically the growth of Heisenberg operators, in large disordered spin chains using matrix product operator dynamics to scan across the…
