旋转Goldstone模的解限制：2+1D超导nematic liquid crystal
Deconfining the rotational Goldstone mode: the superconducting nematic liquid crystal in 2+1D
摘要：
戈德斯通定理指出，每个自发破缺的对称生成元都应该有一个无质量模式。晶体中没有这种转动模式，但是超导量子向列相应该带有转动的Goldstone模式。通过将热2D缺陷介导的熔化理论推广到2+1D量子对偶性，在从固体到固体的量子相变中出现的旋转模式作为一种解除禁闭现象出现，具有不寻常的性质，即旋转模式的刚度完全起源于双位错凝聚体。
英文摘要：
The Goldstone theorem states that there should be a massless mode for each spontaneously broken symmetry generator. There is no such rotational mode in crystals, however superconducting quantum nematics should carry rotational Goldstone modes. By generalization of thermal 2D defect mediated melting theory into a 2+1D quantum duality, the emergence of the rotational mode at the quantum phase transition from the solid to the nematic arises as a deconfinement phenomenon, with the unusual property that the stiffness of the rotational mode originates entirely in the dual dislocation condensate.
