Web23 feb. 2024 · All-optical helicity dependent switching (AO-HDS), deterministic control of magnetization by circularly polarized laser pulses, allows to efficiently manipulate spins without the need of a magnetic field. However, AO-HDS in ferromagnetic metals so far requires many laser pulses for fully switching their magnetic states. Using a combination …

Helicity plays a key role in … WebThe helicity formalism has been developed by Jacob and Wick (1959) for relativistic description of scattering of particles with spin and the decay of particles and resonant …
WebThe property which has been called left-handed and right-handed here is called "helicity". The helicity of a particle is defined as the ratio m s /s, or the z-component of spin divided by the magnitude of the spin. By this definition in this case, the helicity is +1 for a right-handed antineutrino and -1 for a left-handed neutrino. WebThe helicity in elementary particle physics is conceived as the projection of the spin onto the direction of motion [ 24 ]. It has been conjectured by Afanasiev and Stepanovsky that the helicity defined in this way and the helicity are not equivalent.
WebThe helicity of a particle is defined as the projection of a spin vector in the direction of its momentum vector, Therefore, if a particle's spin vector points in the same direction as the momentum vector, the helicity is positive, and if they point in opposite directions, the helicity is negative.
Thus, helicity is just the projection of the spin onto the direction of linear momentum. The helicity of a particle is positive (" right-handed") if the direction of its spin is the same as the direction of its motion and negative ("left-handed") if opposite. Helicity is conserved.
