Separable Skyrme interactions and quasiparticle RPA [PDF]
Physics of Atomic Nuclei, 2003 A finite rank separable approximation for the quasiparticle RPA with Skyrme interactions is applied to study the low lying quadrupole and octupole states in some S isotopes and giant resonances in some spherical nuclei. It is shown that characteristics calculated within the suggested approach are in a good agreement with available experimental data.

Isoscalar Giant Octupole Resonance ISGOR of 116Cd using Self-Consistent Skyrme QRPA
East European Journal of Physics, 2023 Collective models based on the random phase approximation (RPA) are widely used to accurately depict collective modes of response. They can quickly calculate the strength function for the entire nuclear mass range.

Second RPA with Skyrme Interaction [PDF]
Journal of Physics: Conference Series, 2011 The Second Random Phase Approximation (RPA) is a natural extension of RPA obtained by introducing more general excitation operators where two particle-two hole configurations, in addition to the one particle-one hole ones, are considered. Some Second RPA results with Skyrme force in 16O are presented.

Nuclear dipole polarizability from mean-field modeling constrained by chiral effective field theory
Physics Letters B, 2018 We construct a new Skyrme interaction Skχm⁎ by fitting the equation of state and nucleon effective masses in asymmetric nuclear matter from chiral two- and three-body forces as well as the binding energies of finite nuclei.

Emergent Magnetic Field and Nonzero Gyrovector of the Toroidal Magnetic Hopfion
physica status solidi (RRL) – Rapid Research Letters, Volume 17, Issue 12, December 2023., 2023 The toroidal hopfion in the cylindrical magnetic dot is considered and dependencies of the hopfion gyrovector components on the dot sizes are calculated. The calculation method is based on the concept of the emergent magnetic field. The hopfion emergent field and gyrovector can be used for calculations of the topological and skyrmion Hall effects of ...
