偶极费米气体的Hartree-Fock-Bogoliubov理论

Hartree-Fock-Bogoliubov Theory of Dipolar Fermi Gases

Cheng Zhao, Lei Jiang, Xunxu Liu, W. M. Liu, Xubo Zou, Han Pu

摘要:

我们建立了一个完全自洽的Hartree-Fock-Bogoliubov理论,描述了一个无自旋的费米气体与长程相互作用。我们将这一理论应用到一个系统的均匀偶极费米极性分子,这引起了人们的广泛关注,最近,由于快速的实验进展,在实现这样的系统。通过对各向异性超流序参量和临界温度$T_{c}$的计算,我们发现,对于极性分子,只要适当的相互作用强度,就可以实现“高$T_c$“超流.此外,我们还表明,Fock交换相互作用的存在下,增强超流配对。

英文摘要:

We construct a fully self-consistent Hartree-Fock-Bogoliubov theory that describes a spinless Fermi gas with long-range interaction. We apply this theory to a system of uniform dipolar fermionic polar molecules, which has attracted much attention recently, due to rapid experimental progress in achieving such systems. By calculating the anisotropic superfluid order parameter, and the critical temperature $T_{c}$, we show that, "hign $T_c$" superfluid can be achieved with a quite modest value of interaction strength for polar molecules. In addition, we also show that the presence of the Fock exchange interaction enhances superfluid pairing.
