Dynamic critical behavior of the XY model in small-world networks
Kateryna Medvedyeva, Petter Holme, Petter Minnhagen +1
The critical behavior of the XY model on small-world network is investigated by means of dynamic Monte Carlo simulations. We use the short-time relaxation scheme, i.e., the critica…
Comment on ``Loss of Superconducting Phase Coherence in YBa_2Cu_3O_7 Films: Vortex-Loop Unbinding and Kosterlitz-Thouless Phenomena''
Kateryna Medvedyeva, Beom Jun Kim, Petter Minnhagen
Recently, Kotzler et al. measured the frequency-dependent conductance for YBa_2Cu_3O_7 and interpreted their results as evidences that the decay of the superfluid density is caused…
Splitting of the superconducting transition in the two weakly coupled 2D XY models
Kateryna Medvedyeva, Beom Jun Kim, Petter Minnhagen
The frequency and temperature T dependent complex conductivity of two weakly coupled 2D XY models subject to the RSJ dynamics is studied through computer simulations. A dou…
Ubiquitous finite-size scaling features in IV characteristics of various dynamic XY models in two dimensions
Kateryna Medvedyeva, Beom Jun Kim, Petter Minnhagen
Two-dimensional (2D) XY model subject to three different types of dynamics, namely Monte Carlo, resistivity shunted junction (RSJ), and relaxational dynamics, is numerically simula…
Analysis of current-voltage characteristics of two-dimensional superconductors: finite-size scaling behavior in the vicinity of the Kosterlitz Thouless transition
Kateryna Medvedyeva, Beom Jun Kim, Petter Minnhagen
It has been suggested [Pierson et al., Phys. Rev. B 60, 1309 (1999); Ammirata et al., Physica C 313, 225 (1999)] that for 2D superconductors there exists a phase transition with th…
