Relaxation dynamics of an isolated large-spin Fermi gas far from equilibrium
Ulrich Ebling, Jasper Simon Krauser, Nick Fläschner +4
A fundamental question in many-body physics is how closed quantum systems reach equilibrium. We address this question experimentally and theoretically in an ultracold large-spin Fe…
Giant spin oscillations in an ultracold Fermi sea
Jasper Simon Krauser, Ulrich Ebling, Nick Fläschner +5
Collective behavior in many-body systems is the origin of many fascinating phenomena in nature ranging from swarms of birds and modeling of human behavior to fundamental magnetic p…
Coherent multi-flavour spin dynamics in a fermionic quantum gas
Jasper Simon Krauser, Jannes Heinze, Nick Fläschner +3
Microscopic spin interaction processes are fundamental for global static and dynamical magnetic properties of many-body systems. Quantum gases as pure and well isolated systems off…
Multi-band spectroscopy of ultracold fermions: Observation of reduced tunneling in attractive Bose-Fermi mixtures
J. Heinze, S. Götze, J. S. Krauser +5
We perform a detailed experimental study of the band excitations and tunneling properties of ultracold fermions in optical lattices. Employing a novel multi-band spectroscopy for f…
Detecting the Amplitude Mode of Strongly Interacting Lattice Bosons by Bragg Scattering
U. Bissbort, S. Götze, Y. Li +6
We report the first detection of the Higgs-type amplitude mode using Bragg spectroscopy in a strongly interacting condensate of ultracold atoms in an optical lattice. By the compar…
