Spectral gaps for the linear surface wave model in periodic channels
Fedor Bakharev, Keijo Ruotsalainen, Jari Taskinen
We consider the linear water-wave problem in a periodic channel which consists of infinitely many identical containers connected with apertures of width . Motivated by applicati…
A gap in the spectrum of the Neumann-Laplacian on a periodic waveguide
F. L. Bakharev, S. A. Nazarov, K. M. Ruotsalainen
We will study the spectral problem related to the Laplace operator in a singularly perturbed periodic waveguide. The waveguide is a quasi-cylinder with contains periodic arrangemen…
Three real-space discretization techniques in electronic structure calculations
T. Torsti, T. Eirola, J. Enkovaara +13
A characteristic feature of the state-of-the-art of real-space methods in electronic structure calculations is the diversity of the techniques used in the discretization of the rel…
