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…
Projection Optimization Method for Open-Dissipative Quantum Fluids and its Application to a Single Vortex in a Photon Bose-Einstein Condensate
Joshua Krauß, Marcos Alberto Gonçalves dos Santos Filho, Francisco Ednilson Alves dos Santos +1
Open dissipative systems of quantum fluids have been well studied numerically. In view of a complementary analytical description we extend here the variational optimization method…
Finite-temperature degenerate perturbation theory for bosons in optical lattices
Felipe Taha Sant'Ana, Axel Pelster, Francisco Ednilson Alves dos Santos
Bosonic atoms confined in optical lattices can exist in two different phases, Mott-insulator and superfluid, depending on the strength of the system parameters, such as the on-site…
