Quantum quenches in the anisotropic spin-1/2 Heisenberg chain: different approaches to many-body dynamics far from equilibrium
Peter Barmettler, Matthias Punk, Vladimir Gritsev +2
Recent experimental achievements in controlling ultracold gases in optical lattices open a new perspective on quantum many-body physics. In these experimental setups it is possible…

Polaron to molecule transition in a strongly imbalanced Fermi gas
M. Punk, P. T. Dumitrescu, W. Zwerger
A single down spin Fermion with an attractive, zero range interaction with a Fermi sea of up-spin Fermions forms a polaronic quasiparticle. The associated quasiparticle weight vani…
