The variational inclusion of spin-orbit coupling in self-consistent field (SCF) calculations requires a generalised two-component framework, which permits the single-determinant wave function to completely break spin symmetry. individual components molecular g-tensor are commonly obtained from separate SCF solutions that align magnetic moment along one three principal tensor axes. However, this...

The first single chain magnet (SCM) based on orbitally degenerate hexacyanoosmate(III) was prepared. The high values of energy barriers for the [Mn(acacen)Os(CN)6](2-) complex of 81 and 48.4 K are the result of interplay of three axes anisotropic coupling of [Os(CN)6](3-) with zero field splitted Mn(3+).

In this article, we prove existence results for common fixed points of two or three relatively asymptotically regular mappings satisfying the orbital continuity of one of the involved maps on ordered orbitally complete metric spaces. We furnish suitable examples to demonstrate the validity of the hypotheses of our results.

We present results for the hybrid meson spectrum produced by gluonic excitations in full QCD using Wilson fermions. For the spin-exotic mesons with J P C = 1 −+ , 0 +− , and 2 +− we find the lightest state to be 1 −+ with a mass of 1.9(2) GeV. Results obtained for orbitally excited mesons are also presented.
