The P2– F2 pairing model is generally considered to provide an adequate description of the superfluid states of neutron matter at densities some 2-3 times that of saturated symmetrical nuclear matter. The problem of solving the system of BCS gap equations expressing the P2– F2 model is attacked with the aid of the separation approach. This method, developed originally for quantitative study of ...

It is shown that in N ≃ Z nuclei the effects of isovector pairing and the symmetry energy are intimately related. In particular, in the odd-odd N = Z nuclei these two effect are essentially equal in magnitude, causing near degeneracy of the lowest T = 1 and T = 0 states and appearance of the T = 1 ground state isospin in many such nuclei. To illustrate the validity of the considerations present...

The authors propose that unconventional superconductivity in weakly interacting multiband systems can come along with finite energy Cooper pairing formed by electrons having different magnetic quantum numbers.

Influence of asymmetry on superfluidity of nuclear matter with triplet–singlet pairing of nucleons (in spin and isospin spaces) is considered within the framework of a Fermi–liquid theory. Solutions of self–consistent equations for the critical temperature and the energy gap at T = 0 are obtained with the use of Skyrme effective nucleon interaction. It is shown, that if the chemical potentials ...

Algorithms for joint subcarrier pairing and power allocation are investigated in order to maximize the worst-case energy efficiency (EE) in dual-hop decode-and-forward (DF) relay networks in the presence of an active eavesdropper. Accordingly, we study the impact of number of subcarriers on the trade-off in performance between the EE and the spectrum efficiency (SE). The formulated EE optimizat...

The paper compares the K-dependence of the superconducting gap in different doping ranges. The fine behavior of the leading edge gap indicates that the pairing susceptibility is peaked at special regions on the Fermi surface. These hot regions are found to be centered away from nominal " hot spots ". This indicates a symmetry breaking below Tc. I attribute this behavior to a signature of the pa...
