Skyrmions and the nuclear force.
The derivation of the nucleon-nucleon force from the Skyrme model is reexamined. Starting from previous results for the potential energy of quasistatic solutions, we show that a calculation using the Born-Oppenheimer approximation properly taking into account the mixing of nucleon resonances, leads to substantial central attraction. We obtain a potential that is in qualitative agreement with ph...
متن کاملNuclear Matter Aspects of Skyrmions
As an alternative approach to the infinite-array description of dense matter in the Skyrme model, we report about the properties of a single skyrmion on a compact 3-sphere of finite radius. The density of this matter can be increased by decreasing the hypersphere radius. As in the array calculations one encounters a transition to a distinct high density phase characterized by a delocalization i...
متن کاملMagnus force on skyrmions in ferromagnets and quantum Hall systems.
The topological solitons, or " skyrmions " , in a planar ferromagnet experience a Magnus force proportional to the product of their velocity and the surrounding magnetization. It has been suggested that the charged quasiparticles near filling factor ν = 1 in the GaAs quantum Hall effect are skyrmions. If so, we might expect this spin-induced Magnus force to act on the quasiparticles in addition...
متن کاملThe Conformations of 1-Thiacyclooctan-3-One Dynamic Nuclear Magnetic Resonance and Force-Field Calculation
The 1H and natural-abundance 13C-NMR spectra of 1-thiacyclooctan-3-one (1) have been measured from 25 to -100°C. Coalescence is observed in the 1H-NMR spectra of (1) at about -80°C, and attributed to ring inversion in a boat-chair conformation, which is the predominant conformation of (1). The free energy of activation (DG¹</s...
