Return Radius and volume of recrystallized material in Ostwald Ripening
Frank Hausser, Evgeny Lakshtanov
Within the framework of the LSW theory of Ostwald ripening the amount of volume of the second (solid) phase that is newly formed by recrystallization is investigated. It is shown,…
Morphological stability of electromigration-driven vacancy islands
Frank Hausser, Philipp Kuhn, Joachim Krug +1
The electromigration-induced shape evolution of two-dimensional vacancy islands on a crystal surface is studied using a continuum approach. We consider the regime where mass transp…
Complex shape evolution of electromigration-driven single-layer islands
Philipp Kuhn, Joachim Krug, Frank Hausser +1
The shape evolution of two-dimensional islands through periphery diffusion biased by an electromigration force is studied numerically using a continuum approach. We show that the i…
Integral Theory for Quasi-Hopf Algebras
Frank Hausser, Florian Nill
We generalize the fundamental structure Theorem on Hopf (bi)-modules by Larson and Sweedler to quasi-Hopf algebras H. If H is finite dimensional this proves the existence and uniqu…
Doubles of Quasi-Quantum Groups
Frank Hausser, Florian Nill
Drinfeld showed that any finite dimensional Hopf algebra \G extends to a quasitriangular Hopf algebra \D(\G), the quantum double of \G. Based on the construction of a so--called di…
Diagonal Crossed Products by Duals of Quasi-Quantum Groups
Frank Hausser, Florian Nill
Let \G be a (weak) quasi-Hopf algebra. Using a two-sided \G-coaction on an algebra \M, we construct what we call the diagonal crossed product as a new associative algebra structure…
