Graph-theory measures capture weak ergodicity breaking on large quantum systems
Heiko Georg Menzler, Rafał Świętek, Mari Carmen Bañuls +1
We study the onset of weak ergodicity violations in closed quantum many-body systems and focus on cases in which they occur through a transition that is controlled by a model param…
Breakdown of bosonic Thouless pump due to interaction in a quasiperiodic lattice
Suman Mondal, Emmanuel Gottlob, Fabian Heidrich-Meisner +1
We investigate the effect of inter-particle interaction on the quantized Thouless pump in the bosonic quasiperiodic Aubry-Andr{é} model and find that the quantization of the pumped…
Hybrid quantum-classical matrix-product state and Lanczos methods for electron-phonon systems with strong electronic correlations: Application to disordered systems coupled to Einstein phonons
Heiko Georg Menzler, Suman Mondal, Fabian Heidrich-Meisner
We present two quantum-classical hybrid methods for simulating the time-dependence of electron-phonon systems that treat electronic correlations numerically exactly and optical-pho…
Charge carrier relaxation dynamics in the one-dimensional Kondo lattice model
Arturo Perez-Romero, Mica Schwarm, Fabian Heidrich-Meisner
A generic question in the field of ultrafast dynamics is concerned with the relaxation dynamics and the subsequent thermalization of optically excited charge carriers. Among severa…
Hierarchy of timescales in a disordered spin- XX ladder
Kadir Çeven, Lukas Peinemann, Fabian Heidrich-Meisner
Understanding the timescales associated with relaxation to equilibrium in closed quantum many-body systems is one of the central focuses in the study of their non-equilibrium dynam…
Graph theory and tunable slow dynamics in quantum East Hamiltonians
Heiko Georg Menzler, Mari Carmen Bañuls, Fabian Heidrich-Meisner
We show how graph theory concepts can provide an insight into the origin of slow dynamics in systems with kinetic constraints. In particular, we observe that slow dynamics is relat…
