Electronic structure calculations have become an essential tool for the interpretation and rationalization of experimental results in chemistry and an integral part of many important branches of science, e.g. material science, molecular biology, pharmacology and astrophysics. One of the most successful electron-structure methods is the coupled cluster (CC) methods. However, applying CC methods in their conventional formulation to large molecular systems is practically impossible due to two major roadblocks: the steep scaling of the computational cost with system size and the slow convergence of the correlation energy with respect to the expansion of the one-electron basis. 


In his PhD studies, Yang Min Wang has developed a new strategy to solve these problems by combining a local correlation method (DEC) with an explicitly correlated method (F12-theory). This work will ultimately push the boundaries of high-precision quantum chemical calculations on large molecular systems.
