Diagonalization of the Landau Hamiltonian with a Periodic Potential via a Galerkin Projection Method and Applications to Topological Band Properties
Rafael Antonio Lainez Reyes, Benjamin Stamm, Hans Peter Büchler
In this paper, we study the numerical computation of eigenfunctions of the Landau Hamiltonian with a periodic potential. We propose a spectral method using the eigenfunctions of th…

Fully guaranteed and computable error bounds on the energy for periodic Kohn-Sham equations with convex density functionals
Andrea Bordignon, Geneviève Dusson, Éric Cancès +3
In this article, we derive fully guaranteed error bounds for the energy of convex nonlinear mean-field models. These results apply in particular to Kohn-Sham equations with convex…
