On flat bands in the -- XXZ sawtooth chain
Vadim Ohanyan, Johannes Richter, Michael Sekania +3
We consider a generalization of the XXZ model on the sawtooth spin chain with Dzyaloshinskii-Moriya interactions in which all exchange constants (symmetric, antisymmetric, and axia…
Evaluating Rapid Makespan Predictions for Heterogeneous Systems with Programmable Logic
Martin Wilhelm, Franz Freitag, Max Tzschoppe +1
Heterogeneous computing systems, which combine general-purpose processors with specialized accelerators, are increasingly important for optimizing the performance of modern applica…
Exact matching as an alternative to propensity score matching
Ekkehard Glimm, Lillian Yau
The comparison of different medical treatments from observational studies or across different clinical studies is often biased by confounding factors such as systematic differences…
An hp Multigrid Approach for Tensor-Product Space-Time Finite Element Discretizations of the Stokes Equations
Nils Margenberg, Markus Bause, Peter Munch
We present a monolithic space-time multigrid method for tensor-product space-time finite element discretizations of the Stokes equations. Geometric and polynomial coarsening o…
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…
Physics-Informed Learning for Time-Resolved Angiographic Contrast Agent Concentration Reconstruction
Noah Maul, Annette Birkhold, Fabian Wagner +5
Three-dimensional Digital Subtraction Angiography (3D-DSA) is a well-established X-ray-based technique for visualizing vascular anatomy. Recently, four-dimensional DSA (4D-DSA) rec…
