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. This system undergoes a superconductor to insulator transition at zero temperature as a function of charging energy. The critical behavior is studied using a Monte Carlo transfer matrix applied to the path‐integral representation of the model and a finite‐size‐scaling analysis of data on small system…

It is found that, unlike the previous studied case of equal interchain and intrachain coupling constants, the Ising-like excitations of the quantum model decouple for large interchain coupling, giving rise to pure Ising model critical behavior for the chirality order parameter and a superconductor-insulator transition in the universality class of the two-dimensional classical $\mathrm{XY}$ model.

The nature of phase transitions in a generalized uniformly frustrated square-lattice model with XY spins suggests the existence of an Ising-like transition, and a finite-size-scaling analysis and a visualization of the ordering conclude that these two transitions are merged into a single one of dominant Ising character.
