Spinning waveforms of scalar radiation in quadratic modified gravity by Adam Falkowski, Panagiotis Marinellis

“…In this framework, we calculate the waveforms for classical scalar radiation emitted in scattering of macroscopic objects, including spin effects. To this end, we use the Kosower–Maybee–O’Connell formalism, with the 5-particle amplitude for scalar emission in matter scattering calculated at tree level using the unitarity-factorization bootstrap techniques. …”

Helicity and Spin of Linearly Polarized Hermite-Gaussian Modes by M. Fernandez-Guasti, J. Hernández

“…These intrinsic angular momentum terms, depending on the criterion, can be associated with spin or orbital momentum. The electric and magnetic contributions to the optical helicity will be shown to cancel out for Hermite-Gaussian modes. …”

Comparative analysis of spins-first and wave functions-first students’ understanding of expressions in quantum mechanics by William D. Riihiluoma, Zeynep Topdemir, John R. Thompson

“…Instructors teaching upper-division quantum mechanics have had two primary options when it comes to textbook choice and thus curriculum sequence: starting with wave functions and the Schrödinger equation, referred to as “wave functions-first;” and starting with discrete spin-1/2 systems and Dirac notation, known as “spins-first” courses. …”

Polarization bistability of vertical-cavity surface-emitting lasers under Larmor precession of electron spins by Nobuhide Yokota, Kazuhiro Ikeda, Satoshi Iba, Takeo Katayama, Hiroshi Yasaka

“…We show that the polarization bistability of VCSELs can be controlled by manipulating electron spins in the active region. We achieve such manipulation by using the transverse external magnetic field, i.e., Larmor precession of electron spins. …”

Hall deflection of spin-current driven skyrmion and its modulation by Yu Wang, Jingguo Hu

“…The regulation controls the magnetization orientation of the ferromagnetic input layer so that the spin current injected vertically into the upper layer can obtain an appropriate lateral spin polarization to suppress the transverse deflection caused by the skyrmion Hall effect, hence ensuring that the spin current drives the skyrmion along the magnetic track steadily. …”
