Far-from-equilibrium field theory of many-body quantum spin systems: Prethermalization and relaxation of spin spiral states in three dimensions
We study theoretically the far-from-equilibrium relaxation dynamics of spin spiral states in
the three-dimensional isotropic Heisenberg model. The investigated problem serves as an …

Nonthermal melting of Néel order in the Hubbard model
We study the unitary time evolution of antiferromagnetic order in the Hubbard model after a
quench starting from the perfect Néel state. In this setup, which is well suited for experiments …

Atomtronics with a spin: Statistics of spin transport and nonequilibrium orthogonality catastrophe in cold quantum gases
We propose to investigate the full counting statistics of nonequilibrium spin transport with an
ultracold atomic quantum gas. The setup makes use of the spin control available in atomic …
