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…
