Nonthermal fixed point for massless scalar field theories

Viktoria Noel, Chuang Huang, Aleksandr N. Mikheev +1

We compute universal scaling exponents and scaling functions for massless scalar field theories far from equilibrium. Using a large- expansion to next-to-leading order, we inves…

Quantum Fisher Information of Driven-Dissipative Systems from Keldysh Path Integrals

Malik Jirasek, Igor Lesanovsky, Viktoria Noel

Driven-dissipative many-body quantum systems can be exploited in quantum enhanced sensing protocols. Here, non-classical correlations may allow one to reach a measurement precision…

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…

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…

Detecting defect dynamics in relativistic field theories far from equilibrium using topological data analysis

Viktoria Noel, Daniel Spitz

We study nonequilibrium dynamics of relativistic -component scalar field theories in Minkowski space-time in a classical-statistical regime, where typical occupation numbers of…

Time-Resolved Rubidium-Assisted Electron Capture by Barium (II) Cation

Axel Molle, Jan Philipp Drennhaus, Viktoria Noel +2

Non-local energy transfer between bound electronic states close to the ionisation threshold is employed for efficient state preparation in dilute atom systems from technological fo…
