Localized magnetic states in Rashba dots
Mircea Crisan, David Sanchez, Rosa Lopez +2
We study the formation of local moments in quantum dots arising in quasi-one dimensional electron wires due to localized spin-orbit (Rashba) interaction. Using an Anderson-like mod…

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…
