Truncated Wigner approximation for spins in continuous phase space
Jens Hartmann, Tom Schlegel, Viktoria Noel +2
We review the truncated Wigner approximation (TWA) for spins as a computationally inexpensive numerical approximation method to describe interacting and / or dissipative many-body…
Path integral approach to the truncated Wigner approximation of driven-dissipative spins
Viktoria Noel, Michael Fleischhauer, Igor Lesanovsky
Phase-space approaches such as the truncated Wigner approximation (TWA) provide an efficient semiclassical framework for performing approximate simulations of the dynamics of open…
The fate of dynamical phase transitions at finite temperatures and in open systems
N. Sedlmayr, M. Fleischhauer, J. Sirker
When a quantum system is quenched from its ground state, the time evolution can lead to non-analytic behavior in the return rate at critical times . Such dynamical phase trans…
Quantum emitters coupled to surface plasmons of a nano-wire: A Green function approach
D. Dzsotjan, A. S. Sorensen, M. Fleischhauer
We investigate a system consisting of a single, as well as two emitters strongly coupled to surface plasmon modes of a nano-wire using a Green function approach. Explicit expressio…
Short-time vs. long-time dynamics of entanglement in quantum lattice models
R. G. Unanyan, D. Muth, M. Fleischhauer
We study the short-time evolution of the bipartite entanglement in quantum lattice systems with local interactions in terms of the purity of the reduced density matrix. A lower bou…
Commuting Heisenberg operators as the quantum response problem: Time-normal averages in the truncated Wigner representation
B. Berg, L. I. Plimak, A. Polkovnikov +3
The applicability of the so-called truncated Wigner approximation (-W) is extended to multitime averages of Heisenberg field operators. This task splits naturally in two. Firstly,…
