Aim: Many-body problems in physics and chemistry are today studied using a variety of methods. On the one hand, the traditional many-body methods such as coupled cluster, configuration-interaction and Monte Carlo methods are continuously being refined and routinely applied to problems in quantum chemistry, nuclear, atomic, molecular and solid-state physics. On the other hand, recent developments in density-functional theory (DFT) have led to their widespread use in physics and chemistry, as a useful alternative to the more rigorous ab initio many-body methods. This workshop aims at bringing together people who work with different quantum-mechanical many-body methods.
