Vortex dynamics in superfluids governed by an interacting gauge theory
Salvatore Butera, Manuel Valiente, Patrik Öhberg
We study the dynamics of a vortex in a quasi two-dimensional Bose gas consisting of light matter coupled atoms forming two-component pseudo spins. The gas is subject to a density d…
A physically based connection between fractional calculus and fractal geometry
Salvatore Butera, Mario Di Paola
We show a relation between fractional calculus and fractals, based only on physical and geometrical considerations. The link has been found in the physical origins of the power-law…
Quantized vortices in interacting gauge theories
Salvatore Butera, Manuel Valiente, Patrik Öhberg
We consider a two-dimensional weakly interacting ultracold Bose gas whose constituents are two-level atoms. We study the effects of a synthetic density-dependent gauge field that a…
