FermiSurfer: Fermi-surface viewer providing multiple representation schemes

FermiSurfer is a newly developed Fermi-surface viewer designed to facilitate the understanding of the physical properties of metals. It can display the Fermi surfaces of a material, color plots of arbitrary k-dependent quantities, the Fermi surface at arbitrary cross sections (Fermi lines), cross- or parallel-eye three-dimensional stereogram views, nodal lines, extremal orbits, and highlight the occupied or empty side of the Fermi surface. In addition, various first-principles software packages can produce input for FermiSurfer. This paper explains how to use FermiSurfer and demonstrates its usefulness by investigating the origin of the anisotropic superconductivity of YNi2B2C. (C) 2019 Elsevier B.V. All rights reserved.
