Minimal relativity and 3 S 1 - 3 D 1 pairing in symmetric nuclear matter

چکیده
We present solutions of the coupled, non-relativistic S1D1 gap equations for neutron-proton pairing in symmetric nuclear matter, and estimate relativistic effects by solving the same gap equations modified according to minimal relativity and using single-particle energies from a DiracBrueckner-Hartree-Fock calculation. As a main result we find that relativistic effects decrease the value of the gap at the saturation density kF = 1.36 fm −1 considerably, in conformity with the lack of evidence for strong neutron-proton pairing in finite nuclei.

Phase Structure and Instability Problem in Color Superconductivity
We address the phase structure of color superconducting quark matter at high quark density. Under the electric and color neutrality conditions there appear various phases as a result of the Fermi surface mismatch among different quark flavors induced by finite strange quark mass; the color-flavor locked (CFL) phase where quarks are all energy gapped, the u-quark superconducting (uSC) phase wher...
متن کاملSuperfluidity with dressed nucleons
The gap equation with dressed propagators is solved in symmetric nuclear matter. Nucleon self-energies are obtained within the self-consistent in medium T matrix approximation. The off-shell gap equation is compared to an effective quasiparticle gap equation with reduced interaction. At normal density, we find a reduction of the superfluid gap from 6.5MeV to 0.45MeV when self-energy effects are...
متن کامل2 00 3 Pairing in nuclear systems with effective Gogny and V low k interactions
The pairing properties of nuclear systems are a sensitive probe of the effective nucleon-nucleon interactions. We compare the 1 S 0 pairing gaps in nuclear and neutron matter derived from the phenomenological Gogny interaction and a renormal-ization group motivated low-momentum V low k interaction extracted from realistic interactions. We find that the pairing gaps predicted by these interactio...

We report variational calculations of symmetric nuclear matter and pure neutron matter, using the new Argonne v18 two-nucleon and Urbana IX threenucleon interactions. At the equilibrium density of 0.16 fm−3 the two-nucleon densities in symmetric nuclear matter are found to exhibit a short-range spinisospin structure similar to that found in light nuclei. We also find that both symmetric nuclear...
