hamiltoniansmode conversionschroedinger equationspectraThe spin-orbit coupling in a deformed system is studied by approximating the Schrdinger equation semiclassically. The discrete character of spin is preserved and WKB techniques are used for the coupled two-component wave equations. Thus, contrary to ...
If spin-orbit coupling is considered as a perturbation, the total Hamiltonian decouples into a spin-free (referred as Hsr for a scalar relativistic Hamiltonian)2 and a spin-orbit part: H = Hsr + Hso. The electrostatic and spin-orbit interactions are in general computed independently. The corre...

Spin–orbit coupling In such a wurtzite heterostructure the electrons are allowed to be polarized by the spin–orbit interaction, since both structural and crystal inversion symmetries are broken. The corresponding Hamiltonian for electrons in thec-plane is: ...

An extensive introduction to spin-orbit coupling (SOC) is presented, starting from a discussion of the phenomenological operators and general chemical importance of SOC to studies of chemical reactions. Quantitative SOC operators are discussed, and the symmetry properties of the SOC Hamiltonian important...
Rashba spin–orbit couplingelectron–phonon interactionWe 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...
