旋转超固体的非经典转动惯量
Nonclassical rotational inertia for a supersolid under rotation
摘要：
正如Leggett [4]所提出的，晶体的超固体性由非经典转动惯量（NCRI）性质表征。利用Josserand，Pomeau和Rica [5]提出的量子晶体模型，我们证明了NCRI的发生.这是通过分析上述模型的基态来完成的，该模型与球体填充问题有关，然后推导出惯性动量的理论公式。我们推断一个较低的估计NCRI分数，这是一个里程碑的超固体。
英文摘要：
As proposed by Leggett [4], the supersolidity of a crystal is characterized by the Non Classical Rotational Inertia (NCRI) property. Using a model of quantum crystal introduced by Josserand, Pomeau and Rica [5], we prove that NCRI occurs. This is done by analyzing the ground state of the aforementioned model, which is related to a sphere packing problem, and then deriving a theoretical formula for the inertia momentum. We infer a lower estimate for the NCRI fraction, which is a landmark of supersolidity.
