V. Cataudella et al., How the next-nearest-neighbor interactions change the phase diagram of a fully frustrated XY model?, PHYSICA B, 284, 2000, pp. 431-432
We introduce a fully frustrated XY model with nearest-neighbor (nn) and nex
t-nearest-neighbor (nnn) couplings which can be realized in Josephson junct
ion arrays, We study by means of Monte Carlo simulations the phase diagram
for 0 less than or equal to x less than or equal to 1 (x is the ratio betwe
en nnn and nn couplings). (C) 2000 Elsevier Science B.V. All rights reserve
