On the six components of optical angular momentum [PDF]
, 2011 In special relativity the angular momentum is a rank-two antisymmetric tensor with six independent components. Three of these are the familiar generators of spatial rotation, which for light have been studied at length.

Orbital angular momentum-driven anomalous Hall effect
Physical Review B, 2021 Abstract Orbital angular momentum (OAM) plays a central role in regulating the magnetic state of electrons in non-periodic systems such as atoms and molecules. In solids, on the other hand, OAM is usually quenched by the crystal field, and thus, has a negligible effect on magnetisation.

Theoretical analyses on orbital angular momentum modes in conventional graded-index multimode fibre
Scientific Reports, 2017 Orbital angular momentum (OAM) modes are another mode basis to represent spatial modes. There have been increasing interests in exploiting OAM modes in specialty fibres.

On the reversibility of the Meissner effect and the angular momentum puzzle [PDF]
Annals of Physics, 2016 It is generally believed that the laws of thermodynamics govern superconductivity as an equilibrium state of matter. Here we point out that within the conventional BCS-London description of the normal-superconductor transition in the presence of a magnetic field, the transition cannot be reversible, in contradiction with the thermodynamic description ...

Angular Momentum of Phonons and the Einstein–de Haas Effect [PDF]
Physical Review Letters, 2014 We study angular momentum of phonons in a magnetic crystal. In the presence of a spin-phonon interaction, we obtain a nonzero angular momentum of phonons, which is an odd function of magnetization. At zero temperature, phonon has a zero-point angular momentum besides a zero-point energy.

Thermal lens effect with light’s orbital angular momentum
Optics Express, 2022 Thermal lens effect has been well developed and exploited for decades by using the Gaussian intensity distribution of a laser beam. In this paper, a new thermal lens effect by using a laser beam with Orbital Angular Momentum (OAM) is proposed. We find that the dynamic process for the formation of the OAM-thermal lens has reda rapid change towards the ...

, 2003 Spin angular momentum of photons, and the associated polarisation of light, has been known of for many years. However, it is only over the last decade or so that physically realisable laboratory light beams have been used to study the orbital angular ...
