Fluctuation contribution to the specific heat in non-Fermi models for superconductivity
I. Tifrea, I. Grosu, M. Crisan
We investigate the fluctuation contribution to the specific heat of a two-dimensional superconductor with a non-Fermi normal state described by a Anderson Green's function $G(k,iω)…

Flow-Equations for the Model of Hybridized Bosons and Fermions
C. P. Moca, I. Tifrea, M. Crisan
Using the flow-equations method we showed analytically the occurence of dispersion for the local bosons in a model of hybridized of local bosons and fermions.

Flow-Equation method for a superconductor with magnetic correlations
C. P. Moca, M. Crisan, I. Tifrea
The flow equation method has been used to calculate the energy of single impurity in a superconductor for the Anderson model with . We showed that the energy of the impur…
