Relaxation of antiferromagnetic order in spin-1/2 chains following a quantum quench
Peter Barmettler, Matthias Punk, Vladimir Gritsev +2
We study the unitary time evolution of antiferromagnetic order in anisotropic Heisenberg chains that are initially prepared in a pure quantum state far from equilibrium. Our analys…

Theory of RF-spectroscopy of strongly interacting Fermions
M. Punk, W. Zwerger
We show that strong pairing correlations in Fermi gases lead to the appearance of a gap-like structure in the RF-spectrum, both in the balanced superfluid and in the normal phase a…

Collective mode damping and viscosity in a 1D unitary Fermi gas
M. Punk, W. Zwerger
We calculate the damping of the Bogoliubov-Anderson mode in a one-dimensional two-component attractive Fermi gas for arbitrary coupling strength within a quantum hydrodynamic appro…
