论文摘要
我们采用波函数方法来研究电荷4 $ e $超导体。波函数的结构与电荷2 $ e $超导体的BCS波函数相似。构建了平均田野汉密尔顿和绿色的电荷功能4 $ e $。系统地研究了物理特性,包括状态密度,量规不变性,通量量化,超流体密度和约瑟夫森效应。所有这些结果构成了电荷4 $ e $ sc的微观描述,并且可以作为实验验证的标志。
We apply a wavefunction approach to study the charge 4$e$ superconductor. The wavefunction takes a similar structure to the BCS wavefunction for charge 2$e$ superconductors. The mean-field Hamiltonian and the Green's functions of charge 4$e$ are constructed. The physical properties including the density of states, gauge invariance, flux quantization, superfluid density and Josephson effects are systematically studied. All these results form a microscopic description of the charge 4$e$ SC and can be served as the hallmarks for experimental verifications.
