The Universal Gap-to-Critical Temperature Ratio in Superconductors: a Statistical Mechanical Perspective
Chung-Ru Lee
We propose a statistical mechanical framework to unify the observed relationship between the superconducting energy gap , the pseudogap , and the critical temperature $T…

Generalized Fermi-Dirac Distribution of Exclusive Fermions
Chung-Ru Lee, Chin-Rong Lee
A system of exclusive fermions occurs when two fermions of opposite spin are prohibited from occupying the same quantum level. We derive the distribution of exclusive fermions via…

Determination of the Hamiltonian from the Equations of Motion with Illustration from Examples
Chung-Ru Lee
In this paper, we study the determination of Hamiltonian from a given equations of motion. It can be cast into a problem of matrix factorization after reinterpretation of the syste…
