Engineering Ergodicity-Breaking and Stable Emergent Conservation Laws in a Generic Quantum Many-body System Under Strong Periodic Drive
Sagnik Chaudhuri, Anirban Das, Asmi Haldar +1
A periodically driven quantum many-body system is believed to approach a locally infinite-temperature-like state as dictated by the ergodicity hypothesis, when all the couplings/pa…
Beyond the imbalance: site-resolved dynamics probing resonances in many-body localization
Asmi Haldar, Thibault Scoquart, Fabien Alet +1
We explore the limitations of using imbalance dynamics as a diagnostic tool for many-body localization (MBL) and show that spatial averaging can mask important microscopic features…
Krylov space dynamics of ergodic and dynamically frozen Floquet systems
Luke Staszewski, Asmi Haldar, Pieter W. Claeys +1
In isolated quantum many-body systems periodically driven in time, the asymptotic dynamics at late times can exhibit distinct behavior such as thermalization or dynamical freezing.…
Dynamical freezing in the thermodynamic limit: the strongly driven ensemble
Asmi Haldar, Anirban Das, Sagnik Chaudhuri +5
The ergodicity postulate, a foundational pillar of Gibbsian statistical mechanics predicts that a periodically driven (Floquet) system in the absence of any conservation law heats…
Slow Dynamics and Kohlrausch Relaxation in Isolated Disordered Many-Body Systems
Asmi Haldar
The Kohlrausch(-Williams-Watts) law of stretched exponential relaxation has been observed for more than a century and a half in diverse complex classical systems. Here we show that…
Statistical Mechanics of Floquet Quantum Matter: Exact and Emergent Conservation Laws
Asmi Haldar, Arnab Das
Equilibrium statistical mechanics rests on the assumption of ergodic dynamics of a system modulo the conservation laws of local observables: extremization of entropy immediately gi…
Signatures of quantum phase transitions after quenches in quantum chaotic one-dimensional systems
Asmi Haldar, Krishnanand Mallayya, Markus Heyl +3
Quantum phase transitions are central to our understanding of why matter at very low temperatures can exhibit starkly different properties upon small changes of microscopic paramet…
Dynamical Freezing and Scar Points in Strongly Driven Floquet Matter: Resonance vs Emergent Conservation Laws
Asmi Haldar, Diptiman Sen, Roderich Moessner +1
We consider a clean quantum system subject to strong periodic driving. The existence of a dominant energy scale, , can generate considerable structure in an effective descri…
Onset of Floquet Thermalisation
Asmi Haldar, Roderich Moessner, Arnab Das
In presence of interactions, a closed, homogeneous (disorder-free) many-body system is believed to generically heat up to an `infinite temperature' ensemble when subjected to a per…
Dynamical Many-body Localization and Delocalization in Periodically Driven Closed Quantum Systems
Asmi Haldar, Arnab Das
Quantum interference lies at the heart of several surprising equilibrium and non-equilibrium phenomena in many-body Physics. Here we discuss two recently explored non-equilibrium s…
