Ginzburg-Landau Expansion in Non-Fermi Liquid Superconductors: Effect of the Mass Renormalization Factor
I. Tifrea, J. A. Budagosky Marcilla, J. J. Rodriguez-Nunez
We reconsider the Ginzburg-Landau expansion for the case of a non-Fermi liquid superconductor. We obtain analytical results for the Ginzburg-Landau functional in the critical regio…
Two-dimensional dilute Bose gas in the normal phase
P. Pieri, G. C. Strinati, I. Tifrea
We consider a two-dimensional dilute Bose gas above its superfluid transition temperature. We show that the t-matrix approximation corresponds to the leading set of diagrams in the…
Magnetic instability of a two-dimensional Anderson non-Fermi liquid
I. Tifrea, I. Grosu, M. Crisan
We show that in the Anderson model for a two-dimensional non-Fermi liquid a magnetic instability can lead to the itinerant electron ferromagnetism. The critical temperature and the…
Renormalization group approach of itinerant electron systems near the Lifshitz point
C. P. Moca, I. Tifrea, M. Crisan
Using the renormalization approach proposed by Millis for the itinerant electron systems we calculated the specific heat coefficient for the magnetic fluctuations with susce…
Electron-fluctuation interaction in a non-Fermi superconductor
M. Crisan, C. P. Moca, I. Tifrea
We studied the influence of the amplitude fluctuations of a non-Fermi superconductor on the energy spectrum of the 2D Anderson non-Fermi system. The classical fluctuations give a t…
