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…
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…
Quantum to classical relaxation dynamics of the dissipative Rydberg gas
Viktoria Noel, Igor Lesanovsky
We investigate the relaxation dynamics of a Rydberg gas in regimes where coherent processes and dissipation compete. In the strongly dissipative limit, the dynamics is known to be…
Kelvin waves in nonequilibrium universal dynamics of relativistic scalar field theories
Viktoria Noel, Thomas Gasenzer, Kirill Boguslavski
We investigate the different degrees of freedom underlying far-from-equilibrium scaling behaviour in a relativistic, single-component scalar field theory in two and…
Extracting the symmetries of nonequilibrium quantum many-body systems
Aleksandr N. Mikheev, Viktoria Noel, Ido Siovitz +3
Symmetries play a pivotal role in our understanding of the properties of quantum many-body systems. While there are theorems and a well-established toolbox for systems in thermal e…
