Evolution of Spin-Orbital Entanglement with Increasing Ising Spin-Orbit Coupling

open access: yesCondensed Matter, 2020
Several realistic spin-orbital models for transition metal oxides go beyond the classical expectations and could be understood only by employing the quantum entanglement.

Quantum spin dynamics in external classical fields [PDF]

open access: yesEPJ Web of Conferences, 2019
We study the quantum and classical dynamics of spinning particles in the framework of the general-relativistic covariant Dirac theory. The exact Foldy-Wouthuysen transformation for the most general case of a fermion in arbitrary configurations of the ...

Coulomb Problem for Classical Spinning Particles

open access: yesUniverse, 2023
We consider the motion of a weakly relativistic charged particle with an arbitrary spin in central potential e/r in terms of classical mechanics. We show that the spin–orbital interaction causes the precession of the plane of orbit around the vector of total angular momentum.

The Classical Origin of Spin: Vectors Versus Bivectors

open access: yesAxioms
There are two ways of linearizing the Klein–Gordon equation: Dirac’s choice, which introduces a matter–antimatter pair, and a second approach using a bivector, which Dirac did not consider.

Non-equilibrium effects in a Josephson junction coupled to a precessing spin

open access: yes, 2010
We present a theoretical study of a Josephson junction consisting of two s-wave superconducting leads coupled over a classical spin. When an external magnetic field is applied, the classical spin will precess with the Larmor frequency.

A critique of recent semi-classical spin-half quantum plasma theories [PDF]

open access: yes, 2014
Certain recent semi-classical theories of spin-half quantum plasmas are examined with regard to their internal consistency, physical applicability and relevance to fusion, astrophysical and condensed matter plasmas.

NONRELATIVISTIC CLASSICAL MECHANICS FOR SPINNING PARTICLES [PDF]

open access: yesInternational Journal of Modern Physics A, 2005
We study the classical dynamics of nonrelativistic particles endowed with spin. Nonvanishing Zitterbewegung terms appear in the equation of motion also in the small momentum limit. We derive a generalized work-energy theorem which suggests classical interpretations for tunnel effect and quantum potential.

The Fine-Structure Constant in the Bivector Standard Model

open access: yesAxioms
The geometrical view of the electron as a spinning bivector leads to the partitioning of the electron’s energy into internal and external. The reduced Compton wavelength, λ¯C, is taken as the radius of the inertial ring (a disc), while re characterizes ...

Anatomy of a Spin: The Information-Theoretic Structure of Classical Spin Systems

open access: yesEntropy, 2017
Collective organization in matter plays a significant role in its expressed physical properties. Typically, it is detected via an order parameter, appropriately defined for each given system’s observed emergent patterns.
