[en] We provide a tensor calculus for n-number of N = (1, 0) linear multiplets in six dimensions. The coupling of linear multiplets is encoded in a function F that is subject to certain constraints. We provide various rigid and local supersymmetric models depending on the choice of the function F and provide an interesting off-diagonal superinvariant, which leads to an R supergravity upon elimination of auxiliary fields.
[en] We present two types of new deformations of extended supersymmetric mechanics. The first one generalizes SU(2|1) mechanics and encompasses various models of the “curved” SU(2|2) and SU(4|1) mechanics as deformations of the flat mechanics models. Another type is a generalization of the mechanics associated with the multiplets (4, 4, 0) and involving hyper-Kähler d = 1 sigma models in the bosonic sector. This kind of deformation results in models with quaternion-Kähler d = 1 sigma models as the bosonic core. (paper)
[en] A simple method for non-empirical ligand field multiplet calculations for transition metal L-edge spectra is presented. Ligand field splittings and anisotropic scaling factors for Coulomb integrals are obtained from density functional theory. The method is applied to transition metal monoxide solids and nickel and cobalt phthalocyanines molecules and good agreement with experiment is obtained.
[en] We construct SU(2|1), d = 1 supersymmetric models based on the coupling of dynamical and semi-dynamical (spin) multiplets, where the interaction term of both multiplets is defined on the generalized chiral superspace. The dynamical multiplet is defined as a chiral multiplet (2, 4, 2), while the semi-dynamical multiplet is associated with a multiplet (4, 4, 0) of the mirror type. (paper)
[en] It is shown how to incorporate multiplets with central charges in superconformal gravity. The linear and scalar N = 2 multiplets are presented, and the full superconformal action of scalar multiplets with gauged central charge is given. (orig.)
[en] We present a superconformal tensor calculus for an arbitrary number of five dimensional N=2 linear multiplets. We also demonstrate how to construct higher derivative invariants, and produce higher order supersymmetric off-diagonal models. Finally, we show the procedure required for the derivation of the supersymmetric completion of the non-Abelian F"4 action.
