Exotic superconductivity through bosons in a dynamical cluster approximation
(2015-08-07)
We study the instabilities towards (exotic) superconductivity of mixtures of spin-1/2 fermions coupled to scalar bosons on a two-dimensional square lattice with the Dynamical-Cluster-Approximation (DCA) using a numerically ...
Population dynamics in Floquet realisation of Harper-Hofstadter Hamiltonian
(2015-04-21)
We study the recent Floquet-realisation of the Harper-Hofstadter model in a gas of cold bosonic atoms. We study in detail the scattering processes in this system in the weakly interacting regime due to the interplay of ...
