B. C. Mulkerin, C. J. Bradly, H. M. Quiney, A. M. Martin

摘要:

我们解析地确定了两个相互作用的粒子在一个旋转或一个均匀的合成磁场的谐波陷阱中的性质,其中相对哈密顿量的球对称性是保持的。热力学量,如熵和能量通过二阶量子集团展开计算。我们发现,在强相互作用制度的能量是普遍的,但熵的变化作为旋转或合成磁场强度的函数。

英文摘要:

We analytically determine the properties of two interacting particles in a harmonic trap subject to a rotation or a uniform synthetic magnetic field, where the spherical symmetry of the relative Hamiltonian is preserved. Thermodynamic quantities such as the entropy and energy are calculated via the second order quantum cluster expansion. We find that in the strongly interacting regime the energy is universal, however the entropy changes as a function of the rotation or synthetic magnetic field strength.
