Particle impaction efficiency and size distribution in a MSWI super heater tube bundle

Nils Erland L. Haugen, Steinar Kragset, Mette Bugge +2

Particle impaction in the super heater geometry found in the municipal solid waste incinerator (MSWI) of GKS in Schweinfurt, Germany, has been investigated. By using direct numeric…

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…

First-order phase transition in easy-plane quantum antiferromagnets

S. Kragset, E. Smorgrav, J. Hove +2

Quantum phase transitions in Mott insulators do not fit easily into the Landau-Ginzburg-Wilson paradigm. A recently proposed alternative to it is the so called deconfined quantum c…

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…
