    Importance of Fermi Surface in Cooper Pair Formation

    Hello, This problem is about cooper pair formation and what happens with the calculations if there is an attractive potential between electrons but it is not in the presence of a filled fermi surface. 1. Homework Statement Two electrons just above the filled Fermi Surface of a material can...

    Two shallow wells moving together

    Homework Statement Particle is placed in a field of two shallow one-dimensional potential wells approaching each so that: ##V(x,t)=U(x-\frac{L(t)}{2})+U(x+\frac{L(t)}{2})## (Reminder: shallow well is a well that can support only one bound state). At t=-∞ the wells are infinitely far apart...
