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…
Dynamics and correlations at a quantum phase transition beyond Kibble-Zurek
Krishanu Roychowdhury, Roderich Moessner, Arnab Das
Kibble-Zurek theory (KZ) stands out as the most robust theory of defect generation in the dynamics of phase transitions. KZ utilizes the structure of equilibrium states away from t…
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…
Disorder-induced Enhancement of Entanglement Growth in One Dimension: Information Leakage at the scale of localization length
Roopayan Ghosh, Arnab Das
When a group of compactly packed free fermions is allowed to spread over an empty one-dimensional lattice, the spreading particles can create entanglement between different parts o…
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…
