In this talk, we focus on the Hamiltonian description of the effective photon-photon interaction, which allows to include the thermal cloud into the description. By utilising an Exact Diagonalisation approach, we work out how the effective photon-photon interaction modifies the spectrum of the photon gas. As a second case study, we apply our theory to the dimensional crossover from 2D to 1D [3]. In this scenario, we especially focus on the contribution of the thermal cloud and a subsequent comparison with from the Gross-Pitaevskii theory.
