Coulomb instability in hot nuclei with Skyrme interaction

Physical Review C, 1991
Coulomb instability in hot nuclei is discussed, using the Skyrme effective nucleon-nucleon interactions and a mean-field approach based on a finite-temperature real-time Green's-function method. In the calculation, full degeneracy and symmetry corrections are included.

The Skyrme model and the nucleon-nucleon interaction

Nuclear Physics A, 1985
Abstract Some inadequacies in previous descriptions of the low-energy nucleon-nucleon interaction using the Skyrme effective Lagrangian are noted. It is shown that a generalization of the effective Lagrangian and the inclusion of certain quantum corrections leads to an improved description of this interaction.

Nucleon-Nucleon Interaction in the Skyrme Model

Physica Scripta, 1986
The nucleon-nucleon interaction is derived in the Skyrme model for the baryons. The full time dependence of the rotating soliton fields is taken into account and shown to lead to interaction components that do not appear in the static approximation as well as to small corrections to those that do.

Modified Skyrme model and the nucleon-nucleon interaction

Physical Review C, 1993
We present a Skyrme model with modified kinetic-energy terms. The baryon current of the model supports both fractional and integer baryon number solutions. Chiral symmetry breaking renders the fractional baryon number states absolutely confined. In the unbroken phase the solutions bear resemblance to the constitutent quarks of the nonrelativistic quark

Skyrme-Landau parameterization of effective interactions

Nuclear Physics A, 1991
Abstract The positions and the transition strengths of giant multipole resonances (including electric, magnetic, Fermi and Gamow-Teller transitions of the spherical nuclei 16O, 40Ca, 48Ca, 90Zr, 208Pb) are calculated using the random phase approximation based on the Hartree-Fock ground states with our new extended Skyrme-Landau interaction - SL1.

Study of exotic nuclei with the skyrme interaction

Nuclear Physics A, 1978
Abstract The stability (with respect to nucleon emission) of highly neutron-rich nuclei of He, C, O and Si is investigated in the framework of the Hartree-Fock approximation with several sets of Skyrme interactions. The existence (in the sense of stability against decay with the emission of a neutron) of as yet undetected 20 C, 22 C, 28 O and 42 ...

Speed of sound in asymmetric nuclear matter with Skyrme interactions

Physical Review C, 1988
The speed of sound v is calculated for asymmetric nuclear matter within the general framework of a finite temperature Green's function method with normal pair cutoff approximation and Skyrme interactions. A rather strong dependence of v on ..cap alpha.., the asymmetry coefficient, is observed at high density.

Skyrme interaction and spectra of light nuclei

Physical Review C, 1982
The original three-body term in the Skyrme interaction is replaced by a two-body explicit density dependent term to reproduce simultaneously the excited and ground states of nuclei. Care has been taken to remove the spin instability of the Hartree-Fock ground state in nuclear matter and also the antipairing nature of the interaction inherent in the ...

The interaction of Skyrme-like lumps in (2+1) dimensions

Nonlinearity, 1991
Summary: A model is considered in \((2+1)\) spacetime dimensions in which Skyrme- like lump solutions exist. A static lump resembles the instanton solution of the \(O(3)\) sigma model but has a fixed size. Using a collective coordinate method the interaction between two lumps is studied.
