Micromagnetic view on ultrafast magnon generation by femtosecond spin current pulses [PDF]
, 2018 In this Article we discuss a micromagnetic modelling approach to describe the ultrafast spin-transfer torque excitation of coherent and incoherent magnons on the nanoscale.

Generalized model of interacting integrable tops
Journal of High Energy Physics, 2019 We introduce a family of classical integrable systems describing dynamics of M interacting gl N integrable tops. It extends the previously known model of interacting elliptic tops. Our construction is based on the GL N R-matrix satisfying the associative

Classical Spins in Superconductors [PDF]
Progress of Theoretical Physics, 1968 It is shown that there exists a localized excited state in the energy gap in a superconductor with a classical spin. At finite concentration localized excited states around classical spins form an "impurity band". The process of growth of the "impurity band" and its effects on observable quantities are investigated. § I.

Geometric Integrators for Classical Spin Systems [PDF]
Journal of Computational Physics, 1997 Practical, structure preserving methods for integrating classical Heisenberg spin systems are discussed. One of the new integrators, the Lie-Poisson method, is derived based upon a Hamiltonian splitting: it conserves all of the integrals (spin-length and total spin) of the differential equations but the energy.

On classical description of radiation from neutral fermion with anomalous magnetic moment [PDF]
, 2000 Electromagnetic radiation from an uncharged spin 1/2 particle with an anomalous magnetic moment moving in the classical electromagnetic external field originates from quantum spin-flip transitions.

Classical Z_{2} spin liquid on the generalized four-color Kitaev model
Physical Review ResearchWhile U(1) spin liquids have been extensively studied in both quantum and classical regimes, exact classical Z_{2} spin liquids arising from models with nearest-neighbor, bilinear spin interactions are still rare.

Kerr-Newman stress-tensor from minimal coupling
Journal of High Energy Physics, 2020 In this paper, we demonstrate that at leading order in post Minkowskian (PM) expansion, the stress-energy tensor of Kerr-Newman black hole can be recovered to all orders in spin from three sets of minimal coupling: the electric and gravitational minimal ...

Quantum circuits to measure scalar spin chirality
Physical Review Research, 2023 The scalar spin chirality is a three-body physical observable that plays an outstanding role both in classical magnetism, characterizing non-co-planar spin textures, and in quantum magnetism, as an order parameter for chiral spin liquids.

Classical spin systems and the quantum stabilizer formalism: general mappings and applications
, 2009 We present general mappings between classical spin systems and quantum physics. More precisely, we show how to express partition functions and correlation functions of arbitrary classical spin models as inner products between quantum stabilizer states ...
