Binary transition metal dichalcogenide monolayers share common properties such as a direct optical bandgap, spin-orbit splittings of hundreds of meV, light-matter interaction dominated by robust excitons and coupled spin-valley states. Here we demonstrate spin-orbit-engineering in Mo(1-x)WxSe2 alloy monolayers for optoelectronics and applications based on spin- and valley-control. We probe the ...
We report the effect of the two-body, spin-other-orbit interaction on the magnetocrystalline anisotropy energy of the 3d transition metals. The relevant energy differences were computed for bcc Fe, fcc Ni, and hcp Co using a linearized augmented plane wave method to solve the scalar relativistic KohnSham equations in the local spin-density approximation. The spin-otherorbit interaction was inco...
Using the two-loop approximation of chiral perturbation theory, we calculate the momentum and density dependent isovector nuclear spin-orbit strength Vls(p, kf ). This quantity is derived from the spin-dependent part of the interaction energy Σspin = i 2 ~σ · (~q × ~ p )[Uls(p, kf ) − Vls(p, kf )τ3δ] of a nucleon scattering off weakly inhomogeneous isospinasymmetric nuclear matter. We find that...
Recently, Spielman et al have found a new type of Goldstone boson in quantum Hall effect in bilayers. The Goldstone boson is accompanied with a phase transition or broken symmetry. In the vacuum state if there is a broken symmetry, then a massless particle is emitted. Spielman et al have discovered such a quasiparticle. However, it remains to be proved that there is a phase transition associate...
Institute of Physical Chemistry II, University of Erlangen-Nürnberg, D-8520 Erlangen, Germany (Z. Naturforsch. 29 a, 4'19—428 [1974] ; received 16 November 1973) The complete ligand-field, Coulomb interelectronic repulsion, and spin-orbit interaction matrices have been derived for the d5 electron configuration within octahedral (Oh) and tetrahedral (Td) symmetry. The calculations were performed...
