Regularization of Vortex Core Size in Photon BECs due to Harmonic Trap: An Analytical Approach

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 healing length exceeds the experimentally achievable size of the condensate itself. Here we show that a harmonic confinement regularizes the vorte...
