Localization and spectrum of quasiparticles in a disordered fermionic Dicke model
Sebastian Stumper, Junichi Okamoto
We study a fermionic two-band model with the interband transition resonantly coupled to a cavity. This model was recently proposed to explain cavity-enhanced charge transport, but…

Interaction-driven dynamical quantum phase transitions in a strongly correlated bosonic system
Sebastian Stumper, Michael Thoss, Junichi Okamoto
We study dynamical quantum phase transitions (DQPTs) in the extended Bose-Hubbard model after a sudden quench of the nearest-neighbor interaction strength. Using the time-dependent…

Macroscopic boundary effects in the one-dimensional extended Bose-Hubbard model
Sebastian Stumper, Junichi Okamoto
We study the effect of different open boundary conditions on the insulating ground states of the one-dimensional extended Bose-Hubbard model at and near unit filling. To this end,…
