Improved tetrahedron method for the Brillouin-zone integration applicable to response functions

Mitsuaki Kawamura, Yoshihiro Gohda, Shinji Tsuneyuki

We improve the linear tetrahedron method to overcome systematic errors due to overestimations (underestimations) in integrals for convex (concave) functions, respectively. Our meth…
