A new day is dawning for our ability to understand and control the behavior of materials and molecules, thanks to the combination of previously unimaginable theoretical concepts, improved computational capabilities and revolutionary developments in experimentation. Researchers at CCQ are developing the ideas, algorithms and codes that will take our understanding of the quantum mechanics of electrons in molecules and solids to a new level. CCQ is also an international focal point for computational materials science, hosting a lively array of meetings, workshops, conferences and visitor programs.
