论文摘要
SuperSolid是一个呈现长期顺序和剪切刚度为实体的系统,但也支持非疾病的超级流作为超流体。从有效的角度来看,超级固体是用物质阶段确定的,这些阶段与全球$ u(1)$对称性之间自发地转化不变性。通过使用这种对称处方,我们为超固体构建了全息自下而上的模型,并开始研究其热力学和机械性能。更准确地说,我们分析了所有相图的临界温度,冷凝物,剪切模量和粘度的行为。最后,我们成功地将结果与简单的Ginzburg-landau模型进行了比较,用于超弹,从而得出上述可观察物之间的一些通用物理相关性。
A supersolid is a system that presents long-range order and shear rigidity as a solid but which also supports a non-dissipative superflow as a superfluid. From an effective perspective, supersolids are identified with phases of matter that break spontaneously translational invariance together with a global $U(1)$ symmetry. By using this symmetry prescription, we build a holographic bottom-up model for supersolids and we start the investigation of its thermodynamic and mechanical properties. More precisely, we analyze the behaviour of the critical temperature, the condensate, the shear modulus and the viscosity across all the phase diagram. Finally, we successfully compare our results with a simple Ginzburg-Landau model for supersolids deriving some universal physical correlations between the observables mentioned above.
