XDiag: Exact Diagonalization for Quantum Many-Body Systems
Alexander Wietek, Luke Staszewski, Martin Ulaga +6
Exact diagonalization (ED) is a cornerstone technique in quantum many-body physics, enabling precise solutions to the Schrödinger equation for interacting quantum systems. Despite…
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.…
Quench dynamics of stripes and phase separation in the two-dimensional - model
Luke Staszewski, Alexander Wietek
We investigate the fundamental dynamical process of an initial quench of the chemical potential of the two-dimensional - model. Depending on the ground state phase, sharply d…
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…
