Locality of deep thermalisation through the lens of entanglement teleportation
Saptarshi Mandal, Alan Sherry, Sthitadhi Roy
The paper investigates how deep thermalisation—universal quantum state ensembles emerging from measurements—occurs locally or non‑locally in a system split into two causally discon…
Information phases of partial projected ensembles generated from random quantum states and scrambling dynamics
Alan Sherry, Saptarshi Mandal, Sthitadhi Roy
The projected ensemble -- an ensemble of pure states on a subsystem conditioned on projective measurement outcomes on its complement -- provides a finer probe of ergodicity and inf…
Partial projected ensembles and spatiotemporal structure of information scrambling
Saptarshi Mandal, Pieter W. Claeys, Sthitadhi Roy
Thermalisation and information scrambling in out-of-equilibrium quantum many-body systems are deeply intertwined: local subsystems dynamically approach thermal density matrices whi…
Do mixed states exhibit deep thermalisation?
Alan Sherry, Sthitadhi Roy
Deep thermalisation -- where ensembles of pure states on a local subsystem, conditioned on measurement outcomes on its complement, approach universal maximum-entropy ensembles -- r…
Imprints of information scrambling on eigenstates of a quantum chaotic system
Bikram Pain, Ratul Thakur, Sthitadhi Roy
How are the spatial and temporal patterns of information scrambling in locally interacting quantum many-body systems imprinted on the eigenstates of the system's time-evolution ope…
