Stratosphere-troposphere exchange: An angular momentum perspective [PDF]
, 2007 The exchange of axial angular momentum (AM) between stratosphere and troposphere forms an important part of stratosphere–troposphere exchange (STE). Data are used to quantify the related fluxes through an idealized tropopause for specific flux events ...

, 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 ...

Mapping the transverse spin sum rule in position space
Physics Letters BWe discuss in detail the relativistic spatial distribution of transverse angular momentum, including both orbital and intrinsic spin contributions. Using the quantum phase-space formalism, we begin with the definition of the three-dimensional spatial ...

Spin-constrained orbital-angular-momentum control in high-harmonic generation
Physical Review Research, 2019 The interplay between spin and orbital angular momentum in the up-conversion process allows us to control the macroscopic wave front of high harmonics by manipulating the microscopic polarizations of the driving field.

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.

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 ...
