Delocalization in a partially disordered interacting many-body system
Suman Mondal, Fabian Heidrich-Meisner
We study a partially disordered one-dimensional system with interacting particles. Concretely, we impose a disorder potential to only every other site, followed by a clean site. Ou…
Critical quantum dynamics of observables at eigenstate transitions
Simon Jiricek, Miroslav Hopjan, Patrycja Łydżba +2
It is an outstanding goal to unveil the key features of quantum dynamics at eigenstate transitions. Focusing on quadratic fermionic Hamiltonians that exhibit localization transitio…
Enhanced many-body localization in a kinetically constrained model
Karl Royen, Suman Mondal, Frank Pollmann +1
In the study of the thermalization of closed quantum systems, the role of kinetic constraints on the temporal dynamics and the eventual thermalization is attracting significant int…
Interactions enable Thouless pumping in a nonsliding lattice
Konrad Viebahn, Anne-Sophie Walter, Eric Bertok +5
A topological 'Thouless' pump represents the quantised motion of particles in response to a slow, cyclic modulation of external control parameters. The Thouless pump, like the quan…
Thermal and optical conductivity in the Holstein model at half filling and at finite temperature in the Luttinger-liquid and charge-density-wave regime
David Jansen, Fabian Heidrich-Meisner
Electron-phonon interactions play a key role in many branches of solid-state physics. Here, our focus is on the transport properties of one-dimensional systems, and we apply effici…
Phonon-induced breakdown of Thouless pumping in the Rice-Mele-Holstein model
Suman Mondal, Eric Bertok, Fabian Heidrich-Meisner
Adiabatic and periodic variation of the lattice parameters can make it possible to transport charge through a system even without net external electric or magnetic fields, known as…
