A generalization of the one-dimensional frustrated quantum $\mathrm{XY}$ model is considered in which the interchain and intrachain coupling constants of the two infinite $\mathrm{XY}$ (planar rotor) chains have different strengths. The model can describe the superconductor to insulator transition due to charging effects in a ladder of Josephson junctions in a magnetic field with half a flux quantum per plaquette. From a fluctuation-effective action, this transition is expected to be in the…

Phase transitions in the one‐dimensional frustrated quantum XY model and Josephson‐junction ladders
A one‐dimensional quantum version of the frustrated XY (planar rotor) model is considered which can be physically realized as a ladder of Josephson junctions at half a flux quantum per plaquette.

Underdamped Josephson junction arrays are used as model systems to study novel nonlinear effects to probe different nonlinear behavior such as intrinsic localized modes, resonances in fully frustrated arrays, Meissner-like states, and vortex ratchets.
