Radio-frequency driving of an attractive Fermi gas in a one-dimensional optical lattice
Johannes Kombe, Michael Köhl, Corinna Kollath +1
We investigate the response to radio-frequency driving of an ultracold gas of attractively interacting fermions in a one-dimensional optical lattice. We study the system dynamics b…
Decay and revival of a transient trapped Fermi condensate
Timothy Harrison, Martin Link, Alexandra Behrle +6
We study experimentally and theoretically the response of a two-component Fermi condensate in the strongly-interacting regime to a quench of the interaction strength. The quench is…
Higgs mode in a strongly interacting fermionic superfluid
A. Behrle, T. Harrison, J. Kombe +5
Higgs and Goldstone modes are possible collective modes of an order parameter upon spontaneously breaking a continuous symmetry. Whereas the low-energy Goldstone (phase) mode is al…
Slow interaction quench in BCS superconductors: emergence of pre-formed pairs
Johannes Kombe, Jean-Sebastien Bernier, Michael Köhl +1
We investigate the non-equilibrium behavior of BCS superconductors subjected to slow ramps of their internal interaction strength. We identify three dynamical regimes as a function…
