摘要：

The nearest-neighbour XY spin glass on a hypercubic lattice in four dimensions is studied by Monte Carlo simulations. A finite-size scaling analysis of the data leads to a finite-temperature spin glass transition at T-c = 0.95 +/- 0.15. The critical exponents are estimated to be nu(sg) = 0.70 +/- 0.10 and eta(sg) = -0.28 +/- 0.38. The results imply that the lower critical dimensionality for the XY spin glass is less than four.
