补充资料：BCS能隙方程（BCSenergygapequation）
BCS能隙方程（BCSenergygapequation）
在通常情况下，BCS理论定义对势
Δ=-V〈ψ(r,↓)ψ(r,↑)〉
有能隙存在时它代表超导能隙，ψ为场算符，在弱耦合条件下（`N(0)V\lt\lt1`）给出的能隙方程为
$1=N(0)Vint_0^{\hbar\omega}(\epsilon^2 \Delta^2(T))^{-1/2}$
$*th[(\epsilon^2 \Delta^2(T))^{1/2}//2k_BT]d\epsilon$
式中N(0)为T=0K时费米面上一种自旋方向的态密度，V为电子间净吸引势的平均强度，$\hbar$和ωD分别是除以2π的普朗克常数和德拜频率，ε是以费米面为零点的电子能量，kB为玻尔兹曼常数。数值计算的Δ(T)与T的关系见下图，它与多数超导金属的实验结果符合甚好。
在T→Tc和T→0K时的近似结果为：
$\Delta(T)=\Delta(0)-(2\pi\Delta(0)k_BT)^{1/2}*e^{-\Delta(0)//k_BT}$
$(T\lt\ltT_c)$
$\Delta(T)=(1.74)\Delta(0)(1-T//T_c)^{1/2}$
$(T_c-T)\lt\ltT_c$
这里
$\Delta(0)=2\hbar\omega_Dexp(-1//N(0)V)$
