Field-Theoretical description of the crossover between BCS and BEC in a non-Fermi superconductor
C. P. Moca, I. Tifrea, M. Crisan
Using the field-theoretical methods we studied the evolution from BCS description of a non-Fermi superconductor to that of Bose-Einstein condensation (BEC) in one loop approximatio…

Non-Fermi behavior of the disorder electronic system
C. P. Moca, I. Tifrea, M. Crisan
We showed that an electronic system with weak disorder considered in the finite-charge infinite U Hubbard model can present a non-Fermi behavior. The imaginary pert of the self-ene…
