[1312.3292] Spin-orbit coupling in quantum gases.

One of the essential properties of TI's is a strong spin-orbit interaction, which interaction becomes larger the heavier the element. For the well-studied 3d systems the spin-order interaction typically does not play an essential role, which is one of the reasons attention in the condensed matter community has turned to 4d, 5d, and 5f systems.

The formulae of particle current as well as spin- and angular momentum currents are studied for most spin-orbit coupling (SOC) systems. It is shown that the conventional expression of currents in some literatures are not complete for some SOC systems. The particle current in Dresselhaus system must have extra terms in additional to the conventional one, but no extra term for Rashba, Luttinger.

In condensed matter systems, SO coupling is crucial for the spin-Hall effect 1, 2 and topological insulators 3, 4, 5; it contributes to the electronic properties of. Using the phase-space formulation of quantum mechanics, we derive a four-component Wigner equation for a system composed of spin-1/2 fermions (typically, electrons) including the Zeeman effect and the spin-orbit coupling. This Wigner equation is coupled to the appropriate Maxwell equations to form a self-consistent mean-field model. A set of semiclassical Vlasov equations with spin effects is. In this case EPR spectra can only be observed in the ground state manifold of the paramagnetic system. For transition metal ions in the condensed phase the interactions responsible for the large splittings are the crystal-field (CF) splitting and the spin-orbit coupling (SOC). The combined effect of these two interactions removes the orbital.

Dark matter direct detection in materials with spin-orbit coupling.

Spin–orbit (SO) coupling—the interaction between a quantum particle’s spin and its momentum—is ubiquitous in physical systems. In condensed matter systems, SO coupling is crucial for the spin-Hall effect and topological insulators; it contributes to the electronic properties of materials such as GaAs, and is important for spintronic devices.

Semiconductors with $\mathcal{O}(\mathrm{meV})$ band gaps have been shown to be promising targets to search for sub-MeV mass dark matter (DM). In this paper we focus on a class of materials where such narrow band gaps arise naturally as a consequence of spin-orbit coupling (SOC). Specifically, we are interested in computing DM-electron scattering and absorption rates in these materials using. In this context, in view of the recent interest in the interplay between inter-particle interaction and spin-orbit coupling, the central idea in this Research Topic is to bring together high-quality articles on the frontier of Condensed matter physics towards progress from most recent theoretical as well as experimental studies. Spin-orbit coupling plays an important role in determining the properties of solids, and is crucial for spintronics device applications. Conventional spin-orbit coupling arises microscopically from relativ-istic effects described by the Dirac equation, and is described as a single particle band effect. In this.
