Spin-Orbit Coupling and Tensor Forces [PDF]

Progress of Theoretical Physics, 1957
Nous avons cherche si on peut expliquer les forces spin-orbite dans les noyaux complexes comme un effet du 2e ordre des forces tensorielles. Suivant les methodes de Brueckner, nous calculons d’abord une amplitude de reaction modifiee, pour les collisions de deux nucleons au sein de la matiere nucleaire. Nous utilisons la deuxieme approximation de Born,

Recent insights into the molecular mechanism of ubiquinol oxidation by cytochrome bc1

FEBS Open Bio, EarlyView.
The review reflects on the mechanism of the catalytic reaction in cytochrome bc1: the electron bifurcation that involves the separation of two electrons derived from the quinol oxidation to opposite sides of the enzyme across the membrane. This review summarizes the long‐standing effort to understand the mechanism of quinol oxidation catalyzed by ...

Pure gauge spin-orbit couplings [PDF]

The European Physical Journal Plus, 2017
Planar systems with a general linear spin-orbit interaction (SOI) that can be cast in the form of a non-Abelian pure gauge field are investigated using the language of non-Abelian gauge field theory. A special class of these fields that, though a $2\times2$ matrix, are Abelian are seen to emerge and their general form is given.

Domain wall fringe field coupled spin logic

AIP Advances, 2016
A class of spin logic devices based on the spin-orbit induced spin-transfer torques requires magnetic coupling between electrically isolated ferromagnetic elements.

Characterization of the key membrane protein cytochrome Cyc2 from Ghiorsea bivora

FEBS Open Bio, EarlyView.
This study reports the first detailed biochemical analysis of Cyc2TAG1_1, a cytochrome protein involved in microbial iron oxidation. We produced and purified this enzyme in E. coli, then measured its iron‐oxidizing efficiency, and characterized its electrical and structural properties.

Spin-orbit coupling, electron transport and pairing instabilities in two-dimensional square structures

AIP Advances, 2016
Rashba spin-orbit effects and electron correlations in the two-dimensional cylindrical lattices of square geometries are assessed using mesoscopic two-, three- and four-leg ladder structures.

Deep Learning Pose Estimation for Phenotyping of Co‐Occurring Hyperkinetic Movement Disorders

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective To explore whether routine outpatient video combined with deep learning‐based pose estimation and clinically interpretable kinematic features can support multi‐label phenotyping of co‐occurring hyperkinetic movement disorders (HMDs).

Synthetic 3D Spin-Orbit Coupling

Physical Review Letters, 2012
We describe a method for creating a three-dimensional analogue to Rashba spin-orbit coupling in systems of ultracold atoms. This laser induced coupling uses Raman transitions to link four internal atomic states with a tetrahedral geometry, and gives rise to a Dirac point that is robust against environmental perturbations.

Cavity Optomagnonics with Spin-Orbit Coupled Photons [PDF]

Physical Review Letters, 2016
We experimentally implement a system of cavity optomagnonics, where a sphere of ferromagnetic material supports whispering gallery modes (WGMs) for photons and the magnetostatic mode for magnons. We observe pronounced nonreciprocity and asymmetry in the sideband signals generated by the magnon-induced Brillouin scattering of light.

Topological spin textures of exciton-polaritons manipulating by spin-orbit coupling

Results in Optics, 2021
The topological spin textures of exciton-polariton in microcavities are governed by the interplay of the spin-orbit coupling and longitudinal-transverse splitting.
