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…
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…
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…
Universal polarization energies for defects in monolayer, surface and bulk hexagonal boron nitride : A finite-size fragments GW approach
David Amblard, Gabriele D'Avino, Ivan Duchemin +1
We study defect energy levels in hexagonal boron-nitride with varying number of layers using a fragment many-body formalism, taking as examples the paradigmatic carbon-dimer a…
Doping-induced dielectric catastrophe prompts free-carrier release in organic semiconductors
Massimiliano Comin, Simone Fratini, Xavier Blase +1
The control over material properties attainable through molecular doping is essential to many technological applications of organic semiconductors, such as OLED or thermoelectrics.…
