Physically Agnostic Quasinormal Mode Expansion in Time Dispersive Structures:from Mechanical Vibrations to Nanophotonic Resonances
André Nicolet, Guillaume Demésy, Frédéric Zolla +3
Resonances, also known as quasi normal modes (QNM) in the non-Hermitian case, play an ubiquitous role in all domains of physics ruled by wave phenomena, notably in continuum mechan…
Acoustic modal analysis with heat release fluctuations using nonlinear eigensolvers
Varun Hiremath, Jose E. Roman
Closed combustion devices like gas turbines and rockets are prone to thermoacoustic instabilities. Design engineers in the industry need tools to accurately identify and remove ins…
Thick-restarted joint Lanczos bidiagonalization for the GSVD
Fernando Alvarruiz, Carmen Campos, Jose E. Roman
The computation of the partial generalized singular value decomposition (GSVD) of large-scale matrix pairs can be approached by means of iterative methods based on expanding subspa…
A Parallel Direct Eigensolver for Sequences of Hermitian Eigenvalue Problems with No Tridiagonalization
Shengguo Li, Xinzhe Wu, Jose E. Roman +3
In this paper, a Parallel Direct Eigensolver for Sequences of Hermitian Eigenvalue Problems with no tridiagonalization is proposed, denoted by \texttt{PDESHEP}, and it combines dir…
A parallel structured divide-and-conquer algorithm for symmetric tridiagonal eigenvalue problems
Xia Liao, Shengguo Li, Yutong Lu +1
In this paper, a parallel structured divide-and-conquer (PSDC) eigensolver is proposed for symmetric tridiagonal matrices based on ScaLAPACK and a parallel structured matrix multip…
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…
NEP: a module for the parallel solution of nonlinear eigenvalue problems in SLEPc
Carmen Campos, Jose E. Roman
SLEPc is a parallel library for the solution of various types of large-scale eigenvalue problems. In the last years we have been developing a module within SLEPc, called NEP, that…
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…
