The Transition in the Two-Dimensional Step Model: A Kosterlitz-Thouless Transition in Disguise
Peter Olsson, Petter Holme
Evidence for a Kosterlitz-Thouless transition in the 2D step model is obtained from Monte Carlo determinations of the helicity modulus. It is argued that the free energy of a singl…

High-Tc Superconductors in Applied Magnetic Fields Parallel to the CuO Planes: First Order Transition with Slow Onset of Resistivity
Peter Olsson, Petter Holme
The three dimensional uniformly frustrated XY model is used as a model of a high temperature superconductor in an applied magnetic field parallel to the CuO-planes. Through Monte C…

Vortex dynamics for two-dimensional XY models
Beom Jun Kim, Petter Minnhagen, Peter Olsson
Two-dimensional XY models with resistively shunted junction (RSJ) dynamics and time dependent Ginzburg-Landau (TDGL) dynamics are simulated and it is verified that the vortex respo…
