p-wave Pairing in Two-Component Fermi System with Unequal Population: Weak Coupling BCS to Strong Coupling BEC Regimes
Renyuan Liao, Florentin Popescu, Khandker Quader
We study p-wave pairing in a two-component Fermi system with unequal population across weak-coupling BCS to strong-coupling BEC regimes. We find a rich spin triplet p-wave…
P-wave Pairing in Two-Component Fermi Systems with Unequal Population near Feshbach Resonance
R. Liao, F. Popescu, K. Quader
We explore p-wave pairing in a single-channel two-component Fermi system with unequal population near Feshbach resonance. Our analytical and numerical study reveal a rich superflui…
The Crossover from Impurity to Valence Band in Diluted Magnetic Semiconductors: The Role of the Coulomb Attraction by Acceptor
F. Popescu, C. Şen, E. Dagotto +1
The crossover between an impurity band (IB) and a valence band (VB) regime as a function of the magnetic impurity concentration in models for diluted magnetic semiconductors (DMS)…
Magnetic Instabilities and Phase Diagram of the Double-Exchange Model in Infinite Dimensions
R. S. Fishman, F. Popescu, G. Alvarez +3
Dynamical mean-field theory is used to study the magnetic instabilities and phase diagram of the double-exchange (DE) model with Hund's coupling J_H >0 in infinite dimensions. In a…
Dynamical Mean-Field Study of the Ferromagnetic Transition Temperature of a Two-Band Model for Colossal Magnetoresistance Materials
F. Popescu, C. Sen, E. Dagotto
The ferromagnetic (FM) transition temperature (Tc) of a two-band Double-Exchange (DE) model for colossal magnetoresistance (CMR) materials is studied using dynamical mean-field the…
Critical Temperatures of a Two-Band Model for Diluted Magnetic Semiconductors
F. Popescu, Y. Yildirim, G. Alvarez +2
Using Dynamical Mean Field Theory (DMFT) and Monte Carlo (MC) simulations, we study the ferromagnetic transition temperature Tc of a two-band model for Diluted Magnetic Semiconduct…
