摘要翻译:
本文强调了超流Tcs以上玻色流体的非线性旋转磁化率或抗磁性磁化率,对于足够慢的旋转或弱的B场,玻色流体对涡度的响应是不可压缩的。其原因是玻色流体中量子化涡旋的哈密顿量模型中缺少一项。由此产生的磁化率可以解释Chan等人对固体He和Ong等人对铜酸盐超导体的最新观测。

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.
