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…

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…
