Inducing and controlling spin-orbit coupling (SOC) in graphene is key to create topological states of matter, and for the realization of spintronic devices. Placing graphene onto a transition metal dichalcogenid
这个新奇的现象揭示了在拓扑体系中,自旋-轨道耦合(spin-orbit coupling, SOC)的重要作用。 如果大家了解原子物理的话,应该对自旋-轨道耦合并不陌生。简单来说,电子自旋会产生磁矩,这个磁矩与原子轨道产生的磁场之前会发生相互作用(即为磁矩在电磁场中的能量−μ⋅B),引起哈密顿量的修正ΔH∼L⋅S。原子物理...
The preservation and manipulation of a spin state mainly depends on the strength of the spin–orbit interaction. For pristine graphene, the intrinsic spin–orbit coupling (SOC) is only in the order of fewμeV, which makes it almost impossible to be used as an active element in future ...
Spin orbit coupling (SOC) can be regarded as a form of effective magnetic field‘seen’ by the spin of the electron in the rest frame. Based on the notion of effective magnetic field, it will be straightforward to conceive that spin orbit coupling can be a natural, non-magnetic means of...
The composition of the AuX2 electronic states are further analyzed in terms of scalar-relativistic electronic states. The relevance of spinorbit coupling in the spectroscopy of heavy elements is emphasized by comparing the results of this work with experiment and with other scalar-relativistic ...

This progress has reinvigorated the interest of physicists and materials scientists in the development of inversion asymmetric structures, ranging from layered graphene-...

Spin-orbit coupling makes the spin degree of freedom respond to its orbital environment. In solids this yields such intriguing phenomena as a spin splitting of electron states in inversion-asymmetric systems even at zero magnetic field and a Zeeman split
spin–orbitcouplingelectron–phononinteractionWe investigate the effects of electron- phonon and Rashba spin–orbit couplings on the electronic spectrum of pristine graphene charge carriers. We introduce a Fröhlich-type Hamiltonian describing the electron–phonon interaction in spin–orbit-coupled graphene,...
spin–orbit coupling when the direction of propagation of a surface plasmon wave, which intrinsically has unusual transverse spin, determines a scattering direction of spin-carrying photons. This spin–orbit coupling effect is an optical analogue of the spin injection in solid-state spintronic devices...
