Effects of boundaries and density inhomogeneity on states of vortex matter in Bose--Einstein condensates at finite temperature
S. Kragset, E. Babaev, A. Sudbo
Most of the literature on quantum vortices predicting various states of vortex matter in three dimensions at finite temperatures in quantum fluids is based on an assumption of an e…
Preemptive vortex-loop proliferation in multicomponent interacting Bose--Einstein condensates
E. K. Dahl, E. Babaev, S. Kragset +1
We use analytical arguments and large-scale Monte Carlo calculations to investigate the nature of the phase transitions between distinct complex superfluid phases in a two-componen…
Thermal Fluctuations of Vortex Matter in Trapped Bose-Einstein Condensates
S. Kragset, E. Babaev, A. Sudbo
We perform Monte Carlo studies of vortices in three dimensions in a cylindrical confinement, with uniform and nonuniform density. The former is relevant to rotating 4He, the latter…
Instanton correlators and phase transitions in two- and three-dimensional logarithmic plasmas
K. Borkje, S. Kragset, A. Sudbo
The existence of a discontinuity in the inverse dielectric constant of the two-dimensional Coulomb gas is demonstrated on purely numerical grounds. This is done by expanding the fr…
