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…
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…
