Solving Partial Differential Equations with Monte Carlo / Random Walk on an Analog-Digital Hybrid Computer
Dirk Killat, Sven Köppel, Bernd Ulmann +1
Current digital computers are about to hit basic physical boundaries with respect to integration density, clock frequencies, and particularly energy consumption. This requires the…
ExaHyPE: An Engine for Parallel Dynamically Adaptive Simulations of Wave Problems
Anne Reinarz, Dominic E. Charrier, Michael Bader +13
ExaHyPE ("An Exascale Hyperbolic PDE Engine") is a software engine for solving systems of first-order hyperbolic partial differential equations (PDEs). Hyperbolic PDEs are typicall…
A General-relativistic Determination of the Threshold Mass to Prompt Collapse in Binary Neutron Star Mergers
Sven Köppel, Luke Bovard, Luciano Rezzolla
We study the lifetimes of the remnant produced by the merger of two neutron stars and revisit the determination of the threshold mass to prompt collapse, . Using a full…
Geometric model of black hole quantum -portrait, extradimensions and thermodynamics
Antonia M. Frassino, Sven Köppel, Piero Nicolini
Recently a short scale modified black hole metric, known as holographic metric, has been proposed in order to capture the self-complete character of gravity. In this paper we show…
