The application’s greatest appeal
OpenMX is a first-principles software based on optimized localized basis function and pseudopotentials. It can perform fast and high-precision electron state calculations for a variety of material systems such as interfaces and solutions based on density functional theory. High-speed computation of molecular dynamics and structural optimization is possible for large-scale systems, and it also supports hybrid parallelization. The software supports extended functions, including the O(N) method, electric polarizability calculation based on Berry phase, effective screening medium method, NEB method, noncollinear magnetism, spin orbital coupling, Wannier function creation, and electric conduction calculation using nonequilibrium Green’s functions.
