Analog Computing for Molecular Dynamics
Sven Köppel, Alexandra Krause, Bernd Ulmann
Modern analog computers are ideally suited to solving large systems of ordinary differential equations at high speed with low energy consumtion and limited accuracy. In this articl…
Using analog computers in today's largest computational challenges
Sven Köppel, Bernd Ulmann, Lars Heimann +1
Analog computers can be revived as a feasible technology platform for low precision, energy efficient and fast computing. We justify this statement by measuring the performance of…
ADER discontinuous Galerkin schemes for general-relativistic ideal magnetohydrodynamics
Francesco Fambri, Michael Dumbser, Sven Köppel +2
We present a new class of high-order accurate numerical algorithms for solving the equations of general-relativistic ideal magnetohydrodynamics in curved spacetimes. In this paper…
Towards an exascale code for GRMHD on dynamical spacetimes
Sven Köppel
We present the first results on the construction of an exascale hyperbolic PDE engine (ExaHyPE), a code for the next generation of supercomputers with the objective to evolve dynam…
Generalized uncertainty principle and extra dimensions
Sven Köppel, Marco Knipfer, Maximiliano Isi +2
The generalized uncertainty principle (GUP) is a modification of standard quantum mechanics due to Planck scale effects. The GUP has recently been used to improve the short distanc…
