Structure of the vacuum states in the presence of isovector and isoscalar pairing correlations
D. R. Bes, O. Civitarese, E. E. Maqueda +1
The long standing problem of proton-neutron pairing and, in particular, the limitations imposed on the solutions by the available symmetries, is revisited. We look for solutions wi…
Perturbative description of nuclear double beta decay transitions
D. R Bes, O. Civitarese, N. N. Scoccola
A consistent treatment of intrinsic and collective coordinates is applied to the calculation of matrix elements describing nuclear double beta decay transitions. The method, which…
Baby skyrmions on the sphere
N. N. Scoccola, D. R. Bes
We study a model for two-dimensional skyrmions on a sphere of radius L. Such model simulates a skyrmion lattice of density W/(2 πL^2), where W is the skyrmion winding number. We sh…
Lagrangian Becchi-Rouet-Stora-Tyutin treatment of collective coordinates
Juan P. Garrahan, Martin Kruczenski, Daniel R. Bes
The Becchi-Rouet-Stora-Tyutin (BRST) treatment for the quantization of collective coordinates is considered in the Lagrangian formalism. The motion of a particle in a Riemannian ma…
Becchi-Rouet-Stora-Tyutin quantization of a soliton model in 2+1 dimensions
J. P. Garrahan, L. M. Kruczenski, C. L. Schat +2
The Becchi-Rouet-Stora-Tyutin (BRST) method is applied to the quantization of the solitons of the non-linear model in dimensions. We show that this method allows for a…
A Systematic Treatment of Triaxial Systems at High Spins. II
J. P. Garrahan, D. R. Bes
The BRST treatment of triaxial nuclei rotating at high spins, which had been previously developed, is extended to relate states with neighboring values of the angular momentum .…
