The magnetization process of classical Heisenberg magnets with non-coplanar cuboc ground states
Johannes Richter, Heinz-Jürgen Schmidt, Jürgen Schnack
We consider a classical Heisenberg model on the kagomé and the square kagomé lattice, where at zero magnetic field non-coplanar cuboctahedral ground states with twelve sublattices…
Discrete anisotropic curve shortening flow in higher codimension
Klaus Deckelnick, Robert Nürnberg
We introduce a novel formulation for the evolution of parametric curves by anisotropic curve shortening flow in , . The reformulation hinges on a suitable ma…
No short polynomials vanish on bounded rank matrices
Jan Draisma, Thomas Kahle, Finn Wiersig
We show that the shortest nonzero polynomials vanishing on bounded-rank matrices and skew-symmetric matrices are the determinants and Pfaffians characterising the rank. Algebraical…
Loop-gas description of the localized-magnon states on the kagome lattice with open boundary conditions
Andreas Honecker, Johannes Richter, Jürgen Schnack +1
The high-field regime of the spin-s XXZ antiferromagnet on the kagome lattice gives rise to macroscopically degenerate ground states thanks to a completely flat lowest single-magno…
On the implementation of a locally modified finite element method for interface problems in deal.II
Stefan Frei, Thomas Richter, Thomas Wick
In this work, we describe a simple finite element approach that is able to resolve weak discontinuities in interface problems accurately. The approach is based on a fixed patch mes…
On the norm and iterative model order reduction of linear switched systems
Ion Victor Gosea, Athanasios C. Antoulas
A new definition of the norm for linear switched systems is introduced. It is based on appropriately defined time-domain kernels, or equivalently, on infinite contr…
