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…
Strange metal transport from coupling to fluctuating spins
Simone Fratini, Ivan Duchemin, Arnaud Ralko +1
Metals hosting strong electronic interactions, including high-temperature superconductors, behave in ways that do not conform to normal Fermi liquid theory. To pinpoint the microsc…
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…
Static versus dynamically polarizable environments within the many-body formalism
David Amblard, Xavier Blase, Ivan Duchemin
Continuum or discrete polarizable models for the study of optoelectronic processes in embedded subsystems rely mostly on the restriction of the surrounding electronic dielectric re…
