Semi-classical simulation of spin-1 magnets [PDF]
Physical Review Research, 2022 Theoretical studies of magnets have traditionally concentrated on either classical spins, or the extreme quantum limit of spin-1/2. However, magnets built of spin-1 moments are also intrinsically interesting, not least because they can support quadrupole,

Classical limit of higher-spin string amplitudes [PDF]
Journal of High Energy Physics, 2023 It has been shown that a special set of three-point amplitudes between two massive spinning states and a graviton reproduces the linearised stress-energy tensor for a Kerr black hole in the classical limit. In this work we revisit this result and compare

Spin-Hamiltonians-are-languages-ProcRoySocA-supplementary-material.pdf from Classical spin Hamiltonians are context-sensitive languages [PDF]
, 2023 Classical spin Hamiltonians are a powerful tool to model complex systems, characterized by a local structure given by the local Hamiltonians. One of the best understood local structures is the grammar of formal languages, which are central in computer ...

Coulomb Problem for Classical Spinning Particles
Universe, 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.

Numerical simulations of a spin dynamics model based on a path integral approach
Physical Review Research, 2023 Inspired by path integral molecular dynamics, we build a spin model, in terms of spin coherent states, from which we can compute the quantum expectation values of a spin in a constant magnetic field, at finite temperature.

On classical models of Spin [PDF]
Foundations of Physics Letters, 1992 The reason for recalling this old paper is the ongoing discussion on the attempts of circumventing certain assumptions leading to the Bell theorem (Hess-Philipp, Accardi). If I correctly understand the intentions of these Authors, the idea is to make use of the following logical loophole inherent in the proof of the Bell theorem: Probabilities of ...

Classical gravitational spin–spin interaction [PDF]
Classical and Quantum Gravity, 2001 I obtain an exact, axially symmetric, stationary solution of Einstein's equations for two massless spinning particles. The term representing the spin-spin interaction agrees with recently published approximate work. The spin-spin force appears to be proportional to the inverse fourth power of the coordinate distance between the particles.

Electron Spin or ``Classically Non-Describable Two-Valuedness'' [PDF]
, 2007 In December 1924 Wolfgang Pauli proposed the idea of an inner degree of freedom of the electron, which he insisted should be thought of as genuinely quantum mechanical in nature.

Storage of Classical Information in Quantum Spins [PDF]
Physical Review Letters, 2012 Digital magnetic recording is based on the storage of a bit of information in the orientation of a magnetic system with two stable ground states. Here we address two fundamental problems that arise when this is done on a quantized spin: quantum spin tunneling and back-action of the readout process.

Relativistic dissipative spin dynamics in the relaxation time approximation
Physics Letters B, 2021 The concept of the Wigner function is used to construct a semi-classical kinetic theory describing the evolution of the axial current phase-space density of spin-12 particles in the relaxation time approximation.
