QuantumWise develops commercial software for fast and reliable atomic-scale modeling of nanostructures, fully supported and delivered in an easy-to-use interface, tailored from state-of-the-art methods, and developed by experts to the specifications of our customers. Our main product is Atomistix ToolKit (ATK), which offers a homogeneous interface to many different atomic-scale methods, ranging from first-principles methods to tight-binding and classical potentials. The platform contains a graphical user interface, Virtual NanoLab (VNL), which is free for academic users, and allows to connect the GUI to other simulation engines like VASP, Quantum ESPRESSO, or LAMMPS.
