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…
Replica symmetry breaking in spin glasses in the replica-free Keldysh formalism
Johannes Lang, Subir Sachdev, Sebastian Diehl
We show that the algebra of Parisi ultrametric matrices is recovered by the real-time, replica-free, Dyson-Keldysh equations of infinite-range quantum spin glasses in the late time…
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…
Collective excitations and supersolid behavior of bosonic atoms inside two crossed optical cavities
Johannes Lang, Francesco Piazza, Wilhelm Zwerger
We discuss the nature of symmetry breaking and the associated collective excitations for a system of bosons coupled to the electromagnetic field of two optical cavities. For the sp…
