Multiple solutions for the equilibrium populations in BCS superconductors
DV Anghel - Physica A: Statistical Mechanics and its Applications, 2021 - Elsevier
It was recently shown that the BCS formalism leads to several solutions for the energy gap
and the equilibrium quasiparticle distribution, with a phase transition temperature which …

Discrete-time construction of nonequilibrium path integrals on the Kostantinov–Perel'time contour
Rigorous nonequilibrium actions for the many-body problem are usually derived by means
