Electron interaction with the spin angular momentum of the electromagnetic field
We give a simple derivation and expansion of a recently proposed new relativistic interaction between the electron and the spin angular momentum of the electromagnetic field in quantum electrodynamics (QED). Our derivation is based on the work of Møller, who pointed out that, in special relativity, a particle with spin must always have a finite extension. After generalizing Møller’s classical r...
متن کاملElectromagnetic Confinement via Spin–Orbit Interaction in Anisotropic Dielectrics
We investigate electromagnetic propagation in uniaxial dielectrics with a transversely varying orientation of the optic axis, the latter staying orthogonal everywhere in the propagation direction. In such a geometry, the field experiences no refractive index gradients, yet it acquires a transversely modulated Pancharatnam-Berry phase, that is, a geometric phase originating from a spin-orbit int...
متن کاملElectromagnetic Interaction of Anyons in Non-relativistic Quantum Field Theory
The non-relativistic quantum field theoretic lagrangian which describes an anyon system in the presence of an electromagnetic field is identified. A non-minimal magnetic coupling to the Chern-Simons statistical field as well as to the electromagnetic field together with a direct coupling between both fields are the non trivial ingredients of the lagrangian obtained from the non relativistic lim...
متن کاملInteraction of Electromagnetic Radiation with Supercritical Magnetic Field
Three leading terms in the asymptotic expansion of the one-loop polarization operator in a constant magnetic field are found for B >> Bcr , and the corresponding refraction index is shown to depend only on the propagation direction of the photon relative to the external field. It is established, that the refraction index for one of polarization modes unlimitedly grows with the field, while the ...
متن کاملA “hybrid Plane” with Spin-orbit Interaction and Magnetic Field
Investigation of quantum particles confined to manifolds of a mixed dimensionality has a long history starting from [EŠ87]. Recently this problem attracted a new interest connected with possible influence of external fields and/or internal degrees of freedom. In this paper we continue this line of research and study the dynamics of a charged particle with spin 12 , having in mind an electron, w...
