An eigenvalue problem in electronic structure calculations and its
... is studied. In particular, we are interested in a small number of eigenpairs which are in close relation with several material properties. The eigenpairs of interest can be formally expressed as follows: for a given index k, the k-th smallest eigenpair. A numerical approach to the problem, which is ...
