Dissipative quantum systems: from two to many atoms
Dario Poletti, Jean-Sebastien Bernier, Antoine Georges +1
We study the dynamics of bosonic atoms in a double well potential under the influence of dissipation. The main effect of dissipation is to destroy quantum coherence and to drive th…
Emergence of glass-like dynamics for dissipative and strongly interacting bosons
Dario Poletti, Peter Barmettler, Antoine Georges +1
We study the dynamics of a strongly interacting bosonic quantum gas in an optical lattice potential under the effect of a dissipative environment. We show that the interplay betwee…
Emergence of long distance pair coherence through incoherent local environmental coupling
Jean-Sebastien Bernier, Peter Barmettler, Dario Poletti +1
We demonstrate that quantum coherence can be generated by the interplay of coupling to an incoherent environment and kinetic processes. This joint effect even occurs in a repulsive…
Interaction-induced impeding of decoherence and anomalous diffusion
Dario Poletti, Jean-Sebastien Bernier, Antoine Georges +1
We study how the interplay of dissipation and interactions affects the dynamics of a bosonic many-body quantum system. In the presence of both dissipation and strongly repulsive in…
Propagation front of correlations in an interacting Bose gas
Peter Barmettler, Dario Poletti, Marc Cheneau +1
We analyze the quench dynamics of a one-dimensional bosonic Mott insulator and focus on the time evolution of density correlations. For these we identify a pronounced propagation f…
