Universal scaling at non-thermal fixed points of a two-component Bose gas
Markus Karl, Boris Nowak, Thomas Gasenzer
Quasi-stationary far-from-equilibrium critical states of a two-component Bose gas are studied in two spatial dimensions. After the system has undergone an initial dynamical instabi…
Characterization of hyperfine interaction between single electron and single nuclear spins in diamond assisted by quantum beat from the nuclear spin
J. H. Shim, B. Nowak, I. Niemeyer +3
Precise characterization of a hyperfine interaction is a prerequisite for high fidelity manipulations of electron and nuclear spins belonging to a hybrid qubit register in diamond.…
Non-thermal fixed points: universality, topology, & turbulence in Bose gases
Boris Nowak, Sebastian Erne, Markus Karl +3
In these notes we discuss recent developments in the field of non-equilibrium quantum dynamics. Specifically, we consider nearly coherent Bose gases brought far out of equilibrium…
Tuning universality far from equilibrium
Markus Karl, Boris Nowak, Thomas Gasenzer
Possible universal dynamics of a many-body system far from thermal equilibrium are explored. A focus is set on meta-stable non-thermal states exhibiting critical properties such as…
Delocalization of ultracold atoms in a disordered potential due to light scattering
Boris Nowak, Jami J. Kinnunen, Murray J. Holland +1
We numerically study the expansion dynamics of ultracold atoms in a one-dimensional disordered potential in the presence of a weak position measurement of the atoms. We specificall…
Universal dynamics on the way to thermalisation
Boris Nowak, Jan Schole, Thomas Gasenzer
It is demonstrated how a many-body system far from thermal equilibrium can exhibit universal dynamics in passing a non-thermal fixed point. As an example, the process of Bose-Einst…
