Phase diagram of generalized fully frustrated XY model in two dimensions
Petter Minnhagen, Beom Jun Kim, Sebastian Bernhardsson +1
It is shown that the phase diagram of the two-dimensional generalized fully-frustrated XY model on a square lattice contains a crossing of the chirality transition and the Kosterli…
Scaling determination of the nonlinear I-V characteristics for 2D superconducting networks
Petter Minnhagen, Beom Jun Kim, A. Gronlund
It is shown from computer simulations that the current-voltage (-) characteristics for the two-dimensional XY model with resistively-shunted Josephson junction dynamics and M…
Direct Evidence of the Discontinuous Character of the Kosterlitz-Thouless Jump
Petter Minnhagen, Beom Jun Kim
It is numerically shown that the discontinuous character of the helicity modulus of the two-dimensional XY model at the Kosterlitz-Thouless (KT) transition can be directly related…
Phase Transitions in the Two-Dimensional Random Gauge XY Model
Petter Holme, Petter Minnhagen, Beom Jun Kim
The two-dimensional random gauge \xy model, where the quenched random variables are magnetic bond angles uniformly distributed within (), is studied vi…
Spatiotemporal Stochastic Resonance in Fully Frustrated Josephson Ladders
Beom Jun Kim, Mahn-Soo Choi, Petter Minnhagen +3
We consider a Josephson-junction ladder in an external magnetic field with half flux quantum per plaquette. When driven by external currents, periodic in time and staggered in spac…
Anomalous dynamic response in the two-dimensional lattice Coulomb gas model: Effects of pinning
Beom Jun Kim, Petter Minnhagen
It is demonstrated through Monte Carlo simulations that the one component lattice Coulomb gas model in two dimensions under certain conditions display features of an anomalous dyna…
