Sensitivity to perturbations in the three-dimensional Anderson model
Piotr Tokarczyk, Lev Vidmar, Anatoli Polkovnikov +1
We investigate the fidelity susceptibility, which quantifies the sensitivity of single-particle eigenstates to perturbations, in the three-dimensional Anderson model. As a function…

Local integrals of motion encoded in a few eigenstates
J. Pawłowski, P. Łydżba, M. Mierzejewski
Many properties of a quantum system can be obtained from just a single eigenstate of its Hamiltonian. For example, a single eigenstate can be used to determine whether a system is…

Long-lived non-thermal states in pumped one-dimensional systems of hard-core bosons
Patrycja Łydżba, Janez Bonča
We study a unitary time evolution of a symmetry-broken state in a form of a charge density wave in a finite system of interacting hard-core bosons, which can be mapped onto the XXZ…
