Chiral Ordering in the Four-Dimensional XY Spin Glass
The chiral glass behaviour of the nearest-neighbour random-bond XY spin glass
in four dimensions is studied by Monte Carlo simulations. A chiral glass
transition at is found by a finite-size scaling analysis
of the results. The associated chiral correlation-length exponent is estimated
to be and . The values for the chiral
critical temperature and the exponents are very similar to those reported
recently for the spin glass transition in this model.
The results strongly suggest a simultaneous ordering of spin and chirality in
four dimensions.Comment: Rewritten as a regular paper with one additional figure; 5 figures
