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…

The role of atomic interactions in cavity-induced continuous time crystals
Christian H. Johansen, Johannes Lang, Francesco Piazza
We consider continuous time-crystalline phases in dissipative many-body systems of atoms in cavities, focusing on the role of short-range interatomic interactions. First, we show t…
