VASP

The Vienna Ab initio Simulation Package (VASP) is a sophisticated computer program designed for atomic scale materials modeling, focusing on electronic structure calculations and quantum mechanical molecular dynamics from first principles. VASP serves a niche market of researchers and scientists who require precise computational tools for simulating material properties at the atomic level. The software is particularly valuable for those working in fields such as condensed matter physics, materials science, and chemistry. VASP operates on a licensing business model, generating revenue through the sale of software licenses to academic institutions, research organizations, and commercial enterprises. The program is capable of solving complex many-body equations using methods like density functional theory (DFT) and the Hartree-Fock approximation, as well as hybrid functionals that combine these approaches. Additionally, VASP includes advanced functionalities such as GW quasiparticles and many-body perturbation theory, making it a comprehensive tool for researchers seeking to understand the electronic properties of materials. The company also engages with its user base through workshops and training sessions, enhancing the skills of researchers and expanding the software's application scope.
