CASTEP is a leading code based on planewave-pseudopotential density functional theory. CASTEP can calculate a plethora of properties from first-principles, including energies, vibrational properties (such as infra-red and Raman spectra), electronic response properties, NMR parameters and more. A...

Ab Initio Random Structure Searching Ab initio Random Structure Searching (AIRSS) is a very simple, yet powerful and highly parallel, approach to structure prediction. The concept was introduced in 2006 and its philosophy more extensively discussed in 2011 . Random structures - or more precisely...
