Another operator-theoretical proof for the second-order phase transition in the BCS-Bogoliubov model of superconductivity
Shuji Watanabe
In the preceding papers, imposing certain complicated and strong conditions, the present author showed that the solution to the BCS-Bogoliubov gap equation in superconductivity is…
An operator-theoretical study on the BCS-Bogoliubov model of superconductivity near absolute zero temperature
Shuji Watanabe
In the preceding papers the present author gave another proof of the existence and uniqueness of the solution to the BCS-Bogoliubov gap equation for superconductivity from the view…
An operator-theoretical study of the specific heat and the critical magnetic field in the BCS-Bogoliubov model of superconductivity
Shuji Watanabe
In the preceding paper, introducing a cutoff, the present author gave a proof of the statement that the transition to a superconducting state is a second-order phase transition in…
Characterization of point transformations in quantum mechanics
Yoshio Ohnuki, Shuji Watanabe
We characterize point transformations in quantum mechanics from the mathematical viewpoint. To conclude that the canonical variables given by each point transformation in quantum m…
