Polaritonic properties of the Jaynes-Cummings lattice model in two dimensions
Michael Knap, Enrico Arrigoni, Wolfgang von der Linden
Light-matter systems allow to realize a strongly correlated phase where photons are present. In these systems strong correlations are achieved by optical nonlinearities, which appe…
Emission characteristics of laser-driven dissipative coupled-cavity systems
Michael Knap, Enrico Arrigoni, Wolfgang von der Linden +1
We consider a laser-driven and dissipative system of two coupled cavities with Jaynes-Cummings nonlinearity. In particular, we investigate both incoherent and coherent laser drivin…
Variational cluster approach for strongly correlated lattice bosons in the superfluid phase
Michael Knap, Enrico Arrigoni, Wolfgang von der Linden
We extend the variational cluster approach to deal with strongly correlated lattice bosons in the superfluid phase. To this end, we reformulate the approach within a pseudoparticle…
Excitations in disordered bosonic optical lattices
Michael Knap, Enrico Arrigoni, Wolfgang von der Linden
Spectral excitations of ultracold gases of bosonic atoms trapped in one dimensional optical lattices with disorder are investigated by means of the variational cluster approach app…
