Restricted typicality in non-equilibrium quantum many-body systems
Konrad Pawlik, Piotr Sierant, Jakub Zakrzewski
Characterizing the time evolution of generic quantum many-body systems is a fundamental challenge, as representing the exact state requires exponentially scaling computational reso…

Computing eigenpairs of quantum many-body systems with Polfed.jl
Rok Pintar, Konrad Pawlik, Rafał Świętek +5
We present Polfedjl, an open-source Julia package implementing the Polynomially Filtered Exact Diagonalization (POLFED) algorithm for computing mid-spectrum eigenvalues and eige…

Unconventional Thermalization of a Localized Chain Interacting with an Ergodic Bath
Konrad Pawlik, Nicolas Laflorencie, Jakub Zakrzewski
The study of many-body localized (MBL) phases intrinsically links spectral properties with eigenstate characteristics: localized systems exhibit Poisson level statistics and area-l…
