我们报告的结果，从Monte Carlo模拟的二维和三维玻璃在低温下使用平行回火Monte Carlo。在二维空间中，我们找到了零温转变的有力证据。通过有限尺寸标度，我们确定刚度指数θ=−0.39±0.03。在三维空间中，有限温度的转变是确定的，我们发现θ=0.27±0.01，与畴壁重整化群研究的最新结果相一致。
We report results from Monte Carlo simulations of the two- and three-dimensional gauge glass at low temperature using parallel tempering Monte Carlo. In two dimensions, we find strong evidence for a zero-temperature transition. By means of finite-size scaling, we determine the stiffness exponent θ=−0.39±0.03. In three dimensions, where a finite-temperature transition is well established, we find θ=0.27±0.01, compatible with recent results from domain-wall renormalization group studies.
