Quantum phase transitions in superconducting arrays under external magnetic fields
Beom Jun Kim, Gun Sang Jeon, M. -S. Choi +1
We study the zero-temperature phase transitions of two-dimensional superconducting arrays with both the self- and the junction capacitances in the presence of external magnetic fie…
Giant Shapiro steps for two-dimensional Josephson-junction arrays with time-dependent Ginzburg-Landau dynamics
Beom Jun Kim, Petter Minnhagen
Two-dimensional Josephson junction arrays at zero temperature are investigated numerically within the resistively shunted junction (RSJ) model and the time-dependent Ginzburg-Landa…
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…
