Non-Fermi liquid behavior of the electrical resistivity at the ferromagnetic quantum critical point
D. Bodea, M. Crisan, I. Grosu +1
We propose a model for the non-Fermi behavior in the proximity of the quantum phase transition induced by the strong polarization of the electrons due to local magnetic moments. Th…

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…
