Numerical evaluation of two-time correlation functions in open quantum systems with matrix product state methods: a comparison
Stefan Wolff, Ameneh Sheikhan, Corinna Kollath
We compare the efficiency of different matrix product state (MPS) based methods for the calculation of two-time correlation functions in open quantum systems. The methods are the p…
Non-equilibrium metastable state in a chain of interacting spinless fermions with localized loss
Stefan Wolff, Ameneh Sheikhan, Sebastian Diehl +1
We investigate a chain of spinless fermions with nearest-neighbour interactions that are subject to a local loss process. We determine the time evolution of the system using matrix…
Transition between dissipatively stabilized helical states
Simon Essink, Stefan Wolff, Gunter M. Schütz +2
We analyze a spin-1/2 chain which is driven dissipatively at its boundaries. The dissipative driving is modelled by Lindblad jump operators which only act on both boundary sp…
Evolution of two-time correlations in dissipative quantum spin systems: aging and hierarchical dynamics
Stefan Wolff, Jean-Sebastien Bernier, Dario Poletti +2
We consider the evolution of two-time correlations in the quantum XXZ spin-chain in contact with an environment causing dephasing. Extending quasi-exact time-dependent matrix produ…
Dissipative time evolution of a chiral state after a quantum quench
Stefan Wolff, Ameneh Sheikhan, Corinna Kollath
We investigate the dynamics of fermionic atoms in a high-finesse optical resonator after a sudden switch on of the coupling between the atoms and the cavity. The atoms are addition…
Ultracold fermions in a cavity-induced artificial magnetic field
Corinna Kollath, Ferdinand Brennecke
We show how a fermionic quantum gas in an optical lattice and coupled to the field of an optical cavity can self-organize into a state in which the spontaneously emerging cavity fi…
