Optical spectra of small silver clusters with the Bethe-Salpeter formalism: a Reassessment
Xavier Blase, Ivan Duchemin
We study the optical absorption spectra of small Ag_n (n=2,4,6,8) clusters using the Bethe-Salpeter equation (BSE) formalism with a Hamiltonian built from GW quasiparticle energies…
Joint Approximate Diagonalization approach to Quasiparticle Self-Consistent calculations
Ivan Duchemin, Xavier Blase
We introduce an alternative route to quasiparticle self-consistent calculations () on the basis of a Joint Approximate Diagonalization of the one-body Gree…
Anomalous propagators and the particle-particle channel: Bethe-Salpeter equation
Antoine Marie, Pina Romaniello, Xavier Blase +1
The Bethe-Salpeter equation has been extensively employed to compute the two-body electron-hole propagator and its poles which correspond to the neutral excitation energies of the…
Polarizable Continuum Models and Green's Function Formalism: On the Dynamics of the Solvent Electrons
Ivan Duchemin, David Amblard, Xavier Blase
The many-body formalism, for the calculation of ionization potentials or electronic affinities, relies on the frequency-dependent dielectric function built from the electronic…
Reference CC3 Excitation Energies for Organic Chromophores: Benchmarking TD-DFT, BSE/ and Wave Function Methods
Iryna Knysh, Filippo Lipparini, Aymeric Blondel +4
To expand the QUEST database of highly-accurate vertical transition energies, we consider a series of large organic chromogens ubiquitous in dye chemistry, such as anthraquinone, a…
From many-body ab initio to effective excitonic models: a versatile mapping approach including environmental embedding effects
Mauricio Rodríguez-Mayorga, Xavier Blase, Ivan Duchemin +1
We present an original multi-state projective diabatization scheme based on the Green's function formalism that allows the systematic mapping of many-body ab initio calculations on…
