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…

Large-Amplitude Superexchange of High-Spin Fermions in Optical Lattices

Ole Jürgensen, Jannes Heinze, Dirk-Sören Lühmann

We show that fermionic high-spin systems with spin-changing collisions allow to monitor superexchange processes in optical superlattices with large amplitudes and strong spin fluct…

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…

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…

Influence of the particle number on the spin dynamics of ultracold atoms

Jannes Heinze, Frank Deuretzbacher, Daniela Pfannkuche

We study the dependency of the quantum spin dynamics on the particle number in a system of ultracold spin-1 atoms within the single-spatial-mode approximation. We find, for all str…
