Phase transitions in frustrated two-dimensional XY models

· Phys. Rev. B: Condens. Matter; (United States)
We study the fully frustrated XY model on a square lattice with the use of Monte Carlo simulations. We find a phase transition at a finite temperature T/sub I/ with the specific-heat data being consistent with a logarithmic divergence. The helicity modulus UPSILON jumps to zero with a value UPSILON/k/sub B/T> or approx. =2/..pi.. at a T< or approx. =T/sub I/. The application of frustrated XY models to the behavior of coupled Josephson junction arrays is discussed.
