CASTEP (abbreviation for Cambridge Serial Total Energy Package) is a computer program for performing (more) density functional theory (DFT) calculations on the electronic structure and properties of materials. It is a powerful tool for predicting the properties of a wide range of materials, including crystals, surfaces, and molecules, using first-principles calculations based on the fundamental laws of quantum mechanics. CASTEP is widely used in the fields of physics, chemistry, and materials science, and it is particularly useful for predicting the electronic and optical properties of materials, as well as for studying the structure and stability of different phases of matter. It is available for a variety of platforms, including Windows, Linux, and macOS, and it can be downloaded from the CASTEP website. In addition to performing calculations on the electronic structure of materials, CASTEP can also be used to predict the vibrational and thermal properties of materials, and to study the dynamics of processes such as phase transitions and chemical reactions.

It is primarily used for analyzing and processing images and data from scanning probe microscopes (SPMs), such as atomic force microscopes (AFMs) and scanning tunneling microscopes (STMs), but it can also be used for other types of data, such as images from optical microscopes and spectroscopic data. Gwyddion includes a wide range of features and tools for tasks such as data visualization, data analysis, image processing, and curve fitting. It is particularly useful for tasks such as surface characterization, particle sizing, and imaging and analysis of nanostructures. Gwyddion is available for Windows, Linux, and macOS, and it can be downloaded from the Gwyddion website. It is developed and maintained by a community of volunteers, and it is distributed under the GNU General Public License (GPL). Operating system: Cross-platform License: GPL (Free software)

Dirac is a software program for performing quantum mechanical calculations in chemistry and physics. (more) It is used to study the properties of molecules, materials, and other systems at the atomic and subatomic level. Dirac is based on the Dirac equation, a fundamental equation of quantum mechanics that describes the behavior of particles, such as electrons and photons, in terms of wave functions. The software includes a range of features for performing quantum mechanical calculations, such as solving the Schrödinger equation, evaluating energy levels, and calculating wave functions and other quantities. Dirac is developed by a team at the University of Gothenburg in Sweden and is available for Windows, Linux, and Unix operating systems. It is widely used in research and industry to study the properties of chemical and physical systems. Operating system: Linux, FreeBSD, Microsoft Windows, macOS License: LGPL 2.1
