Precipitation hardening involves solutionising, quenching and annealing steps, the latter often at various temperatures. The phenomena observed in Al-Mg-Si alloys are very complicated and partially not well understood. During and after quenching, sol

Quantification of nanoscale density fluctuations in hydrogenated amorphous silicon

Autor: Gericke, Eike, Melskens, Jimmy, Wendt, Robert, Wollgarten, Markus, Hoell, Armin, Lips, Klaus

Publikováno v: Phys. Rev. Lett. 125, 185501 (2020)

The nanostructure of hydrogenated amorphous silicon (a Si:H) is studied by a combination of small-angle X-ray (SAXS) and neutron scattering (SANS) with a spatial resolution of 0.8 nm. The a-Si:H materials were deposited using a range of widely varied

Conjugacy Classes in Kac-Moody Groups and Principal G-Bundles over Elliptic Curves

Autor: Mohrdieck, Stephan, Wendt, Robert

For a simple complex Lie group G the connected components of the moduli space of G-bundles over an elliptic curve are weighted projective spaces. In this note we will provide a new proof of this result using the invariant theory of Kac-Moody groups,

Twisted conjugacy classes, coadjoint orbits of loop groups and D-branes in the WZW-model

Autor: Mohrdieck, Stephan, Wendt, Robert

Publikováno v: manuscripta math., 114, 531-547 (2004)

We show that untwisted respectively twisted conjugacy classes of a compact and simply connected Lie group which satisfy a certain integrality condition correspond naturally to irreducible highest weight representations of the corresponding affine Lie

A character formula for certain representations of loop groups based on non-simply connected Lie groups

Autor: Wendt, Robert

Publikováno v: Math.Z. 247, 549-580 (2004)

I calculate characters of certain representations of loop groups based on non simply connected Lie groups. This gives a generalization of the Kac-Weyl character formula.

Weyl's character formula for non-connected Lie groups and orbital theory for twisted affine Lie algebras

Autor: Wendt, Robert

Publikováno v: J. Funct. Anal. 180 (2001), 31-65

We generalize I. Frenkel's orbital theory for non twisted affine Lie algebras to the case of twisted affine Lie algebras using a character formula for certain non-connected compact Lie groups.
