Correlations in few two-component quantum walkers on a tilted lattice
Saubhik Sarkar, Tomasz Sowiński
We study the effect of inter-component interactions on the dynamical properties of quantum walkers. We consider the simplest situation of two indistinguishable non-interacting walk…
Interspecies entanglement with impurity atoms in a lattice gas
Saubhik Sarkar, Suzanne McEndoo, Dominik Schneble +1
The dynamics of impurity atoms introduced into bosonic gases in an optical lattice have generated a lot of recent interest, both in theory and experiment. We investigate to what ex…
Glassy disorder-induced effects in noisy dynamics of Bose-Hubbard and Fermi-Hubbard systems
Saubhik Sarkar, Ujjwal Sen
We address the effects of quenched disorder averaging in the time-evolution of systems of ultracold atoms in optical lattices in the presence of noise, imposed by of an environment…
Signatures of Many-Body Localization in a Controlled Open Quantum System
Henrik P. Lüschen, Pranjal Bordia, Sean S. Hodgman +7
In the presence of disorder, an interacting closed quantum system can undergo many-body localization (MBL) and fail to thermalize. However, over long times even weak couplings to a…
Light scattering and dissipative dynamics of many fermionic atoms in an optical lattice
Saubhik Sarkar, Stephan Langer, Johannes Schachenmayer +1
We investigate the many-body dissipative dynamics of fermionic atoms in an optical lattice in the presence of incoherent light scattering. Deriving and solving a master equation to…
