Theory for superconductivity in a magnetic field: A local approximation approach
Zhidong Hao
We present a microscopic theory for superconductivity in a magnetic field based on a local approximation approach. We derive an expression for free energy density as a function…

New interpretation for energy gap of the cut-off approximation in the BCS theory of superconductivity
Zhidong Hao
This paper concerns the solution of the self-consistency equation for energy gap parameter in the BCS theory of superconductivity. We show that there exists a well-defi…
