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…
Specific heat of a Fermi system near ferromagnetic quantum phase transition
I. Grosu, D. Bodea, M. Crisan
We calculate the specific heat for an interacting Fermi system near the ferromagnetic phase transition using the Renormalization Group method. The temperature dependence of the spe…
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…
