Classically Spinning Skyrmions

AIP Conference Proceedings, 2011
Skyrmions arise as topological soliton solutions in the Skyrme model which has been shown to be a low energy effective theory of QCD in the large NC limit. If quantized suitably, they can be used to describe structure and properties of nucleons and nuclei.

Classical electrodynamics of spinning particles

Canadian Journal of Physics, 1984
We consider particles with mass, charge, intrinsic magnetic and electric dipole moments, and intrinsic angular momentum in interaction with a classical electromagnetic field. From this action we derive the equations of motion of the position and intrinsic angular momentum of the particle including the radiation reaction, the wave equations of the ...

Classical spin theory

Soviet Physics Journal, 1980
Tensor and vector equations of motion of a classical charged particle with spin have been derived within the framework of the special theory of relativity on the basis of Frenkel's tensor. The anomalous magnetic moment of the particle is considered in a natural manner in deriving the equations.

Spin in Classical and Quantum Theory

Physical Review, 1961
The classical equations of motion of a charged point-particle with intrinsic spin under the influence of an external electromagnetic field are restated and compared with the Heisenberg equations of motion derived from the Dirac theory. The partition of angular momentum between particle and field in the classical theory is contrasted to the Dirac theory

Classical spin and its quantization

Physical Review D, 1985
We develop a new formulation of the quantum mechanics of a relativistic fermion based on the existence of an extended set of underlying classical coordinates. We enlarge the classical theory to a superspace built out of ordinary space-time coordinates and a set of Grassmann coordinates which transform like Majorana spinors and describe a classical spin.

Classical spins in van Hove superconductors

Physical Review B, 1996
We show the existence of the localized excited state in the energy gap of a superconductor described by the van Hove scenario, given by the interaction of the electrons (holes) with a classical spin.

THE QUANTIZATION OF THE CLASSICAL THEORY OF SPINNING PARTICLES

Canadian Journal of Physics, 1951
The classical theory of particles, possessing charge and dipole moment, and moving in an electromagnetic field, is considered on the assumptions that there is no constraint connection between the rotational variables and the velocity of the particle, and that the two invariant squares of the dipole moment six–vector are constants of the motion.

Classical relativistic dynamics of « spin » particles

Il Nuovo Cimento, 1963
By means of a variational principle together with a principle of total angular momentum, the general equations of motion of a particle with internal spin are deduced. This procedure gives rise to a differential equation which the components of the spin angular momentum tensor must satisfy.
