ELSI -- An Open Infrastructure for Electronic Structure Solvers
Victor Wen-zhe Yu, Carmen Campos, William Dawson +16
Routine applications of electronic structure theory to molecules and periodic systems need to compute the electron density from given Hamiltonian and, in case of non-orthogonal bas…

Computation of scattering resonances in absorptive and dispersive media with applications to metal-dielectric nano-structures
Juan C. Araujo-Cabarcas, Carmen Campos, Christian Engström +1
In this paper we consider scattering resonance computations in optics when the resonators consist of frequency dependent and lossy materials, such as metals at optical frequencies.…

Non-linear eigenvalue problems with GetDP and SLEPc: Eigenmode computations of frequency-dispersive photonic open structures
Guillaume Demésy, André Nicolet, Boris Gralak +3
We present a framework to solve non-linear eigenvalue problems suitable for a Finite Element discretization. The implementation is based on the open-source finite element software…
