Self-consistent RPA calculations with Skyrme-type interactions : the skyrmerpa program / G. Colo', L. Cao, N.V. Giai, L. Capelli. - In: COMPUTER PHYSICS COMMUNICATIONS. - ISSN 0010-4655. - 184:1(2013), pp. 142-161. [10.1016/j.cpc.2012.07.016]
Abstract:
Random Phase Approximation (RPA) calculations are nowadays an indispensable tool in nuclear physics studies. We present here a complete version implemented with Skyrme-type interactions, with the spherical symmetry assumption, that can be used in cases where the effects of pairing correlations and of deformation can be ignored. The full self-consistency between the Hartree-Fock mean field and the RPA excitations is enforced, and it is numerically controlled by comparison with energy-weighted sum rules. The main limitations are that charge-exchange excitations and transitions involving spin operators are not included in this version.
