Coupled cluster Coupled cluster (CC) is a numerical technique used for describing many-body systems. Its most common use is as one of several post-Hartree–Fock ab initio quantum chemistry methods in the field of computational chemistry, but it is also used ...

electronic structure models: CCS, CC2, CCSD, CC3, etc.. He introduced contributions to response theory for the purpose of describing electronic excited states. Later he changed the emphasis of his main research interest towards vibrational structure theory and defined a variant of vibrational Coupled cluster (VCC) and developed the theoretical machinery for automatic derivation and implementation of VCC. Moreover, he defined vibrational response theory for various wave function types. All these progress is assembled in the publicly available MidasCpp program suit
