Improving the efficiency of calculations with approximate spectral decompositions of dielectric matrices
Han Yang, Marco Govoni, Giulia Galli
Recently it was shown that the calculation of quasiparticle energies using the approximation can be performed without computing explicitly any virtual electronic states, b…

A finite field approach to solving the Bethe Salpeter equation
Ngoc Linh Nguyen, He Ma, Marco Govoni +2
We present a method to compute optical spectra and exciton binding energies of molecules and solids based on the solution of the Bethe-Salpeter equation (BSE) and the calculation o…

Dielectric dependent hybrid functionals for heterogeneous materials
Huihuo Zheng, Marco Govoni, Giulia Galli
We derive a dielectric-dependent hybrid functional which accurately describes the electronic properties of heterogeneous interfaces and surfaces, as well as those of three- and two…
