Observable- and state-selective prethermalization and bounds on prethermal lifetimes
C. L. Sriram, Soumya Kanti Pal, Lea F. Santos
Prethermalization describes long-lived intermediate regimes that precede equilibrium and can dominate experimentally accessible dynamics. Here, we show that a separation of spectra…

Fragmented ETH and Ensemble Inequivalence
C. L. Sriram, Soumya Kanti Pal, Lea F. Santos
We investigate thermalization in finite quantum systems with strong long-range interactions. Nearly conserved quantities inherited from the fully connected limit organize the Hilbe…

Emergent Thermalization Thresholds in Unitary Dynamics of Inhomogeneously Disordered Quantum Systems
Soumya Kanti Pal, C L Sriram, Shamik Gupta
Inspired by the avalanche scenario for many-body localization (MBL) instability, we reverse the conventional set-up and ask whether a large weakly-disordered chain can thermalize a…
