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…
