Tc以上的玻色流体:不可压缩涡旋流体和“超固体”
Bose Fluids Above Tc: Incompressible Vortex Fluids and "Supersolidity"
摘要:
本文强调,非线性的旋转或抗磁性的磁化率是玻色流体的超流Tcs以上的特点,并为足够慢的旋转或弱的B-字段相当于不可压缩的响应涡。其原因是缺少一项在传统上接受的模型哈密顿量的量子化涡的玻色流体。由此产生的磁化率可以解释Chan等人最近对固体He和Ong等人对铜酸盐超导体的观察。
英文摘要:
This paper emphasizes that non-linear rotational or diamagnetic susceptibility is characteristic of Bose fluids above their superfluid Tcs, and for sufficiently slow rotation or weak B-fields amounts to an incompressible response to vorticity. The cause is a missing term in the conventionally accepted model Hamiltonian for quantized vortices in the Bose fluid. The resulting susceptibility can account for recent observations of Chan et al on solid He, and Ong et al on cuprate superconductors.
