Solution to the Modified Helmholtz Equation for Arbitrary Periodic Charge Densities
Autor: Miriam Winkelmann, Edoardo Di Napoli, Daniel Wortmann, Stefan Blügel
Publikováno v: Frontiers in Physics, Vol 8 (2021)
We present a general method for solving the modified Helmholtz equation without shape approximation for an arbitrary periodic charge distribution, whose solution is known as the Yukawa potential or the screened Coulomb potential. The method is an ext

Non-linear Least-Squares Optimization of Rational Filters for the Solution of Interior Hermitian Eigenvalue Problems
Autor: Jan Winkelmann, Edoardo Di Napoli
Publikováno v: Frontiers in Applied Mathematics and Statistics, Vol 5 (2019)
Rational filter functions can be used to improve convergence of contour-based eigensolvers, a popular family of algorithms for the solution of the interior eigenvalue problem. We present a framework for the optimization of rational filters based on a

Perfect Detection of Spikes in the Linear Sub-threshold Dynamics of Point Neurons
Autor: Jeyashree Krishnan, PierGianLuca Porta Mana, Moritz Helias, Markus Diesmann, Edoardo Di Napoli
Publikováno v: Frontiers in Neuroinformatics, Vol 11 (2018)
Spiking neuronal networks are usually simulated with one of three main schemes: the classical time-driven and event-driven schemes, and the more recent hybrid scheme. All three schemes evolve the state of a neuron through a series of checkpoints: equ

As modern massively parallel clusters are getting larger with beefier compute nodes, traditional parallel eigensolvers, such as direct solvers, struggle keeping the pace with the hardware evolution and being able to scale efficiently due to additiona
