Featured topics

Category subtopics (amongst others)
Theoretical background In this category, we collect theory pages from all the different areas VASP offers functionalities. These can also be reached from the corresponding category. For instance, the article on the Blocked-Davidson algorithm is also linked from the electronic minimization page.
Calculation setup This category contains all pages and topics relevant to the computational setup. For instance, installation, files, performance, etc. To learn how to setup your calculation, it is probably best to look for a how-to page, e.g. Band-structure calculation using hybrid functionals.
Electronic minimization Electronic minimization is the central task in many calculations. Here, you find pages describing the self-consistency cycle, different algorithms, e.g., blocked-Davidson algorithm, RMM-DIIS, direct optimization of the orbitals, and related topics like preconditioning, density mixing, etc.
Electronic ground-state properties Band structure, density of states, partial DOS and on-site charge and magnetization (LORBIT), electrostatics, charge density, potential, etc.
Spin degree of freedom Spin-orbit coupling, noncollinear magnetism, spin spirals, constrained magnetism, etc.
Exchange-correlation functionals LDA, GGA, meta-GGA, DFT+U, hybrid functionals, van der Waals functionals.
