我们讨论连续统对称性的自发破缺,其生成元确实明确地依赖于时空坐标。我们澄清破缺对称性和弹性变量在零和有限的温度,和/或有限的密度之间的关系,并显示一般的计数规则,是模型独立确定的对称性破缺模式。我们将其应用到三个有趣的例子:旋转,共形和规范对称。
We discuss spontaneous breaking of continuum symmetries, whose generators do explicitly depend on the spacetime coordinates. We clarify the relation between broken symmetries and elastic variables at both zero and finite temperatures, and/or finite densities, and show the general counting rule that is model-independently determined by the symmetry breaking pattern. We apply it to three intriguing examples: rotational, conformal, and gauge symmetries.
