Semi-empirical many-body formalism of optical absorption in nanosystems and molecules

Semi-empirical many-body formalism of optical absorption in nanosystems and molecules

A computationally efficient Green’s function approach is developed to evaluate the optical properties of nanostructures within a semi-empirical Hubbard model. A GW formalism is applied on top of a tight-binding and mean-field approach. The use of the GW approximation includes key parts of the many-b...
