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…
Quantum critical scaling behavior of deconfined spinons
Flavio S. Nogueira, Steinar Kragset, Asle Sudbo
We perform a renormalization group analysis of some important effective field theoretic models for deconfined spinons. We show that deconfined spinons are critical for an isotropic…
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…
Metal-Insulator Transition in Two- and Three-Dimensional Logarithmic Plasmas
S. Kragset, A. Sudbo, F. S. Nogueira
We consider scaling of the mean square dipole moments in a plasma with logarithmic interactions in a two- and three-dimensional system. In both cases, we establish the existence of…
