Theory of reflectionless scattering modes

WR Sweeney, CW Hsu, AD Stone - Physical Review A, 2020 - APS
We develop the theory of a special type of scattering state in which a set of asymptotic
channels is chosen as inputs, and the complementary set is chosen as outputs, and there is …

NEP: a module for the parallel solution of nonlinear eigenvalue problems in SLEPc

C Campos, JE Roman - ACM Transactions on Mathematical Software …, 2021 - dl.acm.org
SLEPc is a parallel library for the solution of various types of large-scale eigenvalue
problems. Over the past few years, we have been developing a module within SLEPc, called …

Nonlinearizing two-parameter eigenvalue problems

E Ringh, E Jarlebring - SIAM Journal on Matrix Analysis and Applications, 2021 - SIAM
We investigate a technique to transform a linear two-parameter eigenvalue problem into a
nonlinear eigenvalue problem (NEP). The transformation stems from an elimination of one of …

Broyden's method for nonlinear eigenproblems

E Jarlebring - SIAM Journal on Scientific Computing, 2019 - SIAM
Broyden's method is a general method commonly used for nonlinear systems of equations
when very little information is available about the problem. We develop an approach based …

Metamaterial eigenmodes beyond homogenization

A Günzler, C Schumacher, U Steiner… - Optical Materials …, 2022 - opg.optica.org
Metamaterial homogenization theories usually start with crude approximations that are valid

An iterative method for contour-based nonlinear eigensolvers

J Brenneck, E Polizzi - arXiv preprint arXiv:2007.03000, 2020 - arxiv.org
Contour integration techniques have become a popular choice for solving the linear and non-
linear eigenvalue problems. They principally include the Sakurai-Sugiura methods, the …

A structure preserving shift-invert infinite Arnoldi algorithm for a class of delay eigenvalue problems with Hamiltonian symmetry

P Appeltans, W Michiels - SIAM Journal on Matrix Analysis and Applications, 2023 - SIAM
This work considers a class of delay eigenvalue problems that admit a spectrum similar to
that of a Hamiltonian matrix, in the sense that the spectrum is symmetric with respect to both …
