Rho-nucleon tensor coupling and charge-exchange resonances
(Elsevier B.V., 2000-11-23)
The Gamow-Teller resonance in Pb-208 is discussed in the context of a self-consistent RPA, based on the relativistic mean field theory. We inquire on the possibility of substituting the phenomenological Landau-Migdal force ...
Single and double beta decays in the A=100, A=116 and A=128 triplets of isobars
(Elsevier, 2014-01)
In this paper we analyze the ground-state-to-ground-state two-neutrino double beta (2νββ) decays and single EC and β− decays for the A=100 (100Mo–100Tc–100Ru), A=116 (116Cd–116In–116Sn) and A=128 (128Te–128I–128Xe) triplets ...
Probing the quenching of gA by single and double beta decays
(Elsevier, 2013-06)
Ground-state-to-ground-state two-neutrino double beta (2νββ) decays and single beta (EC and β−) decays are studied for the A=100 (100Mo100Tc100Ru), A=116 (116Cd116In116Sn) and A=128 (128Te128I128Xe) nuclear systems by using ...
Counting independent sets in amenable groups
(2023)
Given a locally finite graph Γ, an amenable subgroup G of graph automorphisms acting freely and almost transitively on its vertices, and a G-invariant activity function λ, consider the free energy fG(Γ,λ) of the hardcore ...
Phase diagram study of a dimerized spin-S zig–zag ladder
(IOP Publishing, 2014-07)
The phase diagram of a frustrated spin-S zig–zag ladder is studied through different numerical and analytical methods. We show that for arbitrary S, there is a family of Hamiltonians for which a fully-dimerized state is ...
Configurational lattice dynamics: The phase diagram of Rh − Pd
(American Physical Society, 2005-04)
Free energies of Rh-Pd alloys as functions of both temperature and composition are calculated using quasiharmonic lattice dynamics. The free energy of the disordered solid is determined from an ensemble of a large number ...
Phase transitions with infinitely many absorbing states in complex networks
