Magnetic Fabry-Pérot interferometer for valley filtering in a honeycomb-dice model
F. Bouhadida, L. Mandhour, S. Charfi-Kaddour
Here we theoretically investigate the valley-dependent transmission of particles through a combined electric and magnetic barrier in the model which interpolates between th…
Effect of the Fermi surface reconstruction on the self-energy of the copper-oxide superconductors
B. Bellafi, M. Azzouz, S. Charfi-Kaddour
We calculated the self-energy corrections beyond the mean-field solution of the rotating antiferromagnetism theory using the functional integral approach. The frequency dependence…
Inhomogeneous superconductivity in organic conductors: role of disorder and magnetic field
Sonia Haddad, Samia Charfi-Kaddour, Jean-Paul Pouget
Several experimental studies have shown the presence of spatially inhomogeneous phase coexistence of superconducting and non superconducting domains in low dimensional organic supe…
Disorder-induced superconductivity in ropes of carbon nanotubes
Besma Bellafi, Sonia Haddad, Samia Charfi-Kaddour
We study the interplay between disorder and superconductivity in a rope of metallic carbon nanotubes. Based on the time dependent Ginzburg Landau theory, we derive the superconduct…
Role of the cooling rate in the stability of the superconducting phase of (TMTSF)_2ClO_4
S. Haddad, I. Sfar, S. Charfi-Kaddour +1
The noncentrosymmetric ClO anions of the organic superconductor (TMTSF)ClO order below 24K. The size of domains where the anions are ordered is substantially dependent…
Magnetic field induced singlet - triplet phase transition in quasi one-dimensional organic superconductors
N. Belmechri, G. Abramovici, M. Heritier +2
We propose a theoretical model of quasi-one-dimensional superconductors, with attractive electron-electron interactions dominant in the singlet d-wave channel and sub-dominant in t…
