Regularization of Vortex Core Size in Photon BECs due to Harmonic Trap: An Analytical Approach
Joshua Krauß, Tabitha Bates, Francisco Ednilson Alves dos Santos +1
Quantized vortices are a hallmark of superfluidity. However, in a photon Bose--Einstein condensate, the photon-photon interaction is so weak that in a homogeneous system the healin…
Weakly interacting Bose gases in the canonical ensemble
Jonata S. Soares, Axel Pelster, Arnaldo Gammal
Based on the canonical description of a non-interacting Bose gas, we work out how both thermodynamic and statistical properties change perturbatively with respect to weak two-parti…
From Lasers to Photon Bose--Einstein Condensates: A Unified Description via an Open-Dissipative Bose--Einstein Distribution
Joshua Krauß, Enrico Stein, Axel Pelster
Photon condensation was first experimentally realized in 2010 within a dye-filled microcavity at room temperature. Since then, interest in the field has increased significantly, as…
Emergence of damped-localized excitations of the Mott state due to disorder
R. S. Souza, Axel Pelster, F. E. A. dos Santos
A key aspect of ultracold bosonic quantum gases in deep optical lattice potential wells is the realization of the strongly interacting Mott insulating phase. Many characteristics o…
