The BCS Gap Equation on a Banach Space Consisting of Functions both of the Temperature and of the Wave Vector
Shuji Watanabe
In previous mathematical studies of the BCS gap equation of superconductivity, the gap function was regarded as an element of a space consisting of functions of the wave vector onl…

A mathematical proof that the transition to a superconducting state is a second-order phase transition
Shuji Watanabe
We deal with the gap function and the thermodynamical potential in the BCS-Bogoliubov theory of superconductivity, where the gap function is a function of the temperature only.…
