Zero-temperature equation of state of a two-dimensional bosonic quantum fluid with finite-range interaction
arXiv:1902.00605 · doi:10.3390/condmat4010020
Abstract
We derive the two-dimensional equation of state for a bosonic system of ultracold atoms interacting with a finite-range effective interaction. Within a functional integration approach, we employ an hydrodynamic parametrization of the bosonic field to calculate the superfluid equations of motion and the zero-temperature pressure. The ultraviolet divergences, naturally arising from the finite-range interaction, are regularized with an improved dimensional regularization technique.
