The fate of the Fermi surface coupled to a single-wave-vector cavity mode
Bernhard Frank, Michele Pini, Johannes Lang +1
The electromagnetic field of standing-wave or ring cavities induces a spatially modulated, infinite-range interaction between atoms in an ultracold Fermi gas, with a single wavelen…

Spectral functions of the strongly interacting 3D Fermi gas
Christian H. Johansen, Bernhard Frank, Johannes Lang
Computing dynamical properties of strongly interacting quantum many-body systems poses a major challenge to theoretical approaches. Usually, one has to resort to numerical analytic…
