Classical spin gravitational Compton scattering [PDF]
Journal of High Energy Physics, 2023 We introduce a novel bootstrap method for heavy-mass effective field theory classical Compton scattering amplitudes involving two massless particles and two arbitrary-spin infinite-mass limit particles. Using a suitable ansatz, we deduce new and explicit

Spatiotemporal dynamics of classical and quantum density profiles in low-dimensional spin systems
Physical Review Research, 2022 We provide a detailed comparison between the dynamics of high-temperature spatiotemporal correlation functions in quantum and classical spin models.

Exceptional points in classical spin dynamics. [PDF]
Sci Rep, 2019 AbstractNon-conservative physical systems admit a special kind of spectral degeneracy, known as exceptional point (EP), at which eigenvalues and eigenvectors of the corresponding non-Hermitian Hamiltonian coalesce. Dynamical parametric encircling of the EP can lead to non-adiabatic evolution associated with a state flip, a sharp transition between the ...

Spin and statistics in classical mechanics [PDF]
American Journal of Physics, 2004 The spin–statistics connection is obtained for classical particles. The connection holds within pseudomechanics, a theory of particle motion that extends classical physics to include anticommuting Grassmann variables, and that exhibits classical analogs of both spin and statistics.

Classical spin transitions and absorptive scattering
Journal of High Energy PhysicsWe describe an on-shell, amplitudes-based approach to incorporating radiation absorption effects in the post-Minkowskian scattering of generic, compact, spinning bodies. Classical spinning observables are recovered by extrapolating to large spin, results

Semi-classical quantisation of magnetic solitons in the anisotropic Heisenberg quantum chain
SciPost Physics, 2021 Using the algebro-geometric approach, we study the structure of semi-classical eigenstates in a weakly-anisotropic quantum Heisenberg spin chain. We outline how classical nonlinear spin waves governed by the anisotropic Landau-Lifshitz equation arise ...

Classical potential for general spinning bodies
Journal of High Energy Physics, 2020 In this paper we compute the spin-dependent terms of the gravitational potential for general spinning bodies at the leading Newton’s constant G and to all orders in spin.
