Two-band superconductivity in (AlMg)B2: Critical temperature and isotope exponent as a function of carrier density

On the interband pairing in doped graphane

“…Intraband processes considered in [34] are here not included. An analogous simplified investigation for (AlMg)B 2 has been made in [35]. We have found, that the interband pairing mechanism alone can serve for doped graphane transition temperatures which reach ∼ 100 K at the coupling strength near 1 eV.…”

“…The expected value of W is unknown, however the estimated order seems to be plausible. In the paper [35] for a MgB 2 family system W∼ 2.3 eV has been found. For A x C 60 a value about 0.4 eV for W has been obtained [23], cf.…”

Two-Bands Superconductivity with Intra- and Interband Pairing for Synthetic Superlattices

“…In fact experimental findings show that the scenario where interband pairing is the dominant interaction, proposed by some of us in previous works [39,40], has now an experimental test.…”

“…In previous papers [39,40], we have considered a Hamiltonian with V 1,2 = V , and V 1,1 = V 2,2 = 0, as the interband and intraband pairing potentials, respectively. Here, these conditions are relaxed.…”

“…On the other side the case of pnictides is considered to be the case where intraband coupling can be neglected as we have proposed in the previous work before the discovery of pnictides [40]. Now we focus our interest on the fact that it is important to consider different cases where both intra-band and interband pairing are relevant that will be relevant for novel synthetic superconducting superlattices.…”
