Why Is the Mechanism Underlying the Chiral‐Induced Selectivity Effect Still Challenging?

Advanced Materials, EarlyView.
The chiral‐induced spin selectivity (CISS) effect is observed in many experimental configurations and for different materials. However, there are theoretical challenges in attempting to explain those results. A qualitative framework for explaining all the results is presented.

Transverse spin sum rule of the proton

Physics Letters B, 2020
The transversely-polarized state of a proton with arbitrary momentum is not an eigenstate of transverse angular momentum operator. The latter does not commute with the QCD Hamiltonian.

Measurement of Optical Orbital and Spin Angular Momentum: Implications for Photon Angular Momentum

, 2017
The expression for the total angular momentum carried by a laser optical vortex beam, splits, in the paraxial approximation, into two terms which seem to represent orbital and spin angular momentum respectively.

Spin and Angular Momentum in Strong-Field Ionization [PDF]

Physical Review Letters, 2018
The spin polarization of electrons from multiphoton ionization of Xe by 395 nm circularly polarized laser pulses at 6×10^{13}  W/cm^{2} has been measured. At this photon energy of 3.14 eV the above-threshold ionization peaks connected to Xe^{+} ions in the ground state (J=3/2, ionization potential I_{p}=12.1  eV) and the first excited state (J=1/2, I_ ...

Spin-Orbital momentum decomposition and helicity exchange in a set of non-null knotted electromagnetic fields

, 2017
We calculate analytically the spin-orbital decomposition of the angular momentum using completely non-paraxial fields that have certain degree of linkage of electric and magnetic lines.

Spin and angular momentum in the nucleon

Physical Review D, 2012
Using the covariant spectator theory (CST), we present the results of a valence quark-diquark model calculation of the nucleon structure function f(x) measured in unpolarized deep inelastic scattering (DIS), and the structure functions g1(x) and g2(x) measured in DIS using polarized beams and targets.
