论文摘要
我们在连续破损的对称阶段讨论了欧几里得量子$ O（n）$模型。我们在线性耦合到标量场的存在下，在低温下研究系统。在疾病的所有实现的合奏中，我们都表现出平均值，我们代表了分区函数的一系列时刻的平均自由能。在单循环的近似中，我们证明有一定的时刻集合，导致系统发展关键行为。我们的结果表明，在平衡系统中，假想中疾病的密切相关性会在大型模式下产生通用尺度不变性。
We discuss the Euclidean quantum $O(N)$ model with $N=2$ in a continuous broken symmetry phase. We study the system at low temperatures in the presence of quenched disorder linearly coupled to the scalar field. Performing an average over the ensemble of all realizations of the disorder, we represent the average free energy in terms of a series of the moments of the partition function. In the one-loop approximation, we prove that there is a denumerable collection of moments that lead the system to develop critical behavior. Our results indicate that in an equilibrium system, the strongly correlation of the disorder in imaginary produces generic scale invariance in the massive modes.
