Dissipation of Spin Angular Momentum in Magnetic Switching [PDF]
Physical Review Letters, 2005 Applying one ultrashort magnetic field pulse, we observe up to 10 precessional switches of the magnetization direction in single crystalline Fe films of 10 and 15 atomic layers. We find that the rate at which angular momentum is dissipated in uniform large angle spin precession increases with time and film thickness, surpassing the intrinsic ...

Chiral phonon induced spin polarization
Physical Review Research, 2023 The current understanding of chirality suggests the existence of a connection between structure and angular momentum, including spin. This is particularly emphasized in the chiral induced spin selectivity effect, where chiral structures act as spin ...

Gauge invariant Noether’s theorem and the proton spin crisis
Journal of High Energy Physics, 2018 Due to proton spin crisis it is necessary to understand the gauge invariant definition of the spin and orbital angular momentum of the quark and gluon from first principle.

High-Order Orbital and Spin Hall Effects at the Tight Focus of Laser Beams
Photonics, 2022 In this paper, using a Richards–Wolf method, which describes the behavior of electromagnetic waves at the sharp focus, we show that high-order spin and orbital Hall effects take place at the focal plane of tightly focused laser beams. We reveal that four

Density of optical degrees of freedom : intensity, linear and angular momentum
, 2014 For any optical system, optical eigenmodes describe solutions of Maxwells equations that are orthogonal to each other. In their simplest free space form, these modes correspond, for example, to Bessel, Laguerre-Gaussian or Hermite-Gaussian beams. However,

Angular momentum conservation and phonon spin in magnetic insulators [PDF]
, 2020 We develop a microscopic theory of spin-lattice interactions in magnetic insulators, separating rigid-body rotations and the internal angular momentum, or spin, of the phonons, while conserving the total angular momentum.

On the dragging of light by a rotating medium
, 2007 When light is passing through a rotating medium the optical polarization is rotated. Recently, it has been reasoned that this rotation applies also to the transmitted image.
