Since its early days some 25 years ago, Psi-k has been an inspirational source for the advancement of density functional theory. What started as fundamental effort in theoretical and computational physics has now become an indispensable tool for fundamental as well as applied research used in thousands of laboratories in academia and industry around the globe. The growing Psi-k community and visionaries such as Volker Heine can be proud of this most remarkable accomplishment. Today, this field remains vibrant with an abundance of opportunities and challenges. We at Materials Design are proud to be rooted in this community, which enables us to bring the best state-of-the-art technology to our customers. The team of Materials Design wishes the organizers and all participants a productive, stimulating, and enjoyable conference.
