Disorder, spin-orbit, and interaction effects in dilute
Gregory A. Fiete, Gergely Zarand, Kedar Damle +1
We derive an effective Hamiltonian for in the dilute limit, where can be described in terms of spin …
Positional Disorder, Spin-Orbit Coupling and Frustration in GaMnAs
Gregory A. Fiete, Gergely Zarand, Boldizsar Janko +2
We study the magnetic properties of metallic GaMnAs. We calculate the effective RKKY interaction between Mn spins using several realistic models for the valence band structure of G…
Shiba multiplets due to Mn impurities in MgB_2
Catalin Pascu Moca, Gergely Zarand, Eugene Demler +1
We study the effect of magnetic Mn ions on the two-band superconductor MgB_2, and compute both the total and spin resolved scanning tunneling spectrum in the vicinity of the magnet…
Signatures of interband scattering in spectroscopic experiments on
C. P. Moca, B. Janko
Within a two-band, strong coupling model we analyze SIS-tunneling conductance, Raman scattering and optical conductivity measured on samples. We find that features observed…
Non-Fermi Behavior of the Strongly Correlated Electron Systems
Catalin Pascu Moca
(1) The temperature dependence of the specific heat for a marginal Fermi liquid has been calculated. (2) We calculated the self-energy at T=0 for a two dimensional fermionic system…
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…
