A Scalable Two-Level Domain Decomposition Eigensolver for Periodic Schrödinger Eigenstates in Anisotropically Expanding Domains
Lambert Theisen, Benjamin Stamm
Accelerating iterative eigenvalue algorithms is often achieved by employing a spectral shifting strategy. Unfortunately, improved shifting typically leads to a smaller eigenvalue f…

Domain Decomposition Method for Poisson--Boltzmann Equations based on Solvent Excluded Surface
Abhinav Jha, Benjamin Stamm
In this paper, we develop a domain decomposition method for the nonlinear Poisson-Boltzmann equation based on a solvent-excluded surface widely used in computational chemistry. The…
