Classical mappings of the symplectic model and their application to the theory of large-amplitude collective motion
Abraham Klein, Niels R. Walet
We study the algebra Sp(n,R) of the symplectic model, in particular for the cases n=1,2,3, in a new way. Starting from the Poisson-bracket realization we derive a set of partial di…
The Skyrme model description of the spin-orbit force
R. D. Amado, Bin Shao, Niels R. Walet
We examine the derivation of the spin-orbit force from the Skyrme model. We find substantial agreement with phenomenological potentials. We show that a systematic and simultaneous…
Inertial parameters of the Skyrmion-Skyrmion system with the product ansatz
Bin Shao, Niels R. Walet, R. D. Amado
The kinetic energy of the Skyrmion-Skyrmion system is calculated in the product ansatz. The energy is expanded in a set of rotationally invariant quadratic functions of translation…
Calculation of the properties of the rotational bands of Gd
Pavlos Protopapas, Abraham Klein, Niels R. Walet
We reexamine the long-standing problem of the microscopic derivation of a particle-core coupling model. We base our research on the Klein-Kerman approach, as amended by Dönau and F…
From Skyrmions to NN phaseshifts
Niels R. Walet
We study the phaseshifts in a Hamiltonian obtained from quantization of the collective modes in the Skyrme model. We show that a combination of an adiabatic and diabatic appro…
Quantum theory of large amplitude collective motion and the Born-Oppenheimer method
Abraham Klein, Niels R. Walet
We study the quantum foundations of a theory of large amplitude collective motion for a Hamiltonian expressed in terms of canonical variables. In previous work the separation into…
