Effect of electronic correlation on topological end-states in finite-size graphene nanoribbons
Antoine Honet, Luc Henrard, Vincent Meunier
Finite size armchair graphene nanoribbons (GNR) of different families are theoretically studied using the Hubbard model in both mean-field and GW approximations, including spin cor…
Mean-field approximation of the Hubbard model expressed in a many-body basis
Antoine Honet, Luc Henrard, Vincent Meunier
The effective independent-particle (mean-field) approximation of the Hubbard Hamiltonian is described in a many-body basis to develop a formal comparison with the exact diagonaliza…
Optical modelling of single and multilayer 2D materials and heterostructures
Bruno Majérus, Luc Henrard, Pascal Kockaert
Bidimensional materials are ideally viewed as having no thickness, as their name suggests. Their optical response have been previously modelled by a purely bidimensional surface cu…
Large-area nanoengineering of graphene corrugations for visible-frequency graphene plasmons
Gergely Dobrik, Peter Nemes-Incze, Bruno Majerus +8
Quantum confinement of graphene carriers is an effective way to engineer its properties. It is commonly realized through physical edges that are associated with the deterioration o…
Exact and many-body perturbation solutions of the Hubbard model applied to linear chains
Antoine Honet, Luc Henrard, Vincent Meunier
This study examines how the GW approximation, one of the techniques covered by Green's functions and on many-body approximations (GFMBA), fares compared to the treatment of the Hub…
Semi-empirical many-body formalism of optical absorption in nanosystems and molecules
Antoine Honet, Luc Henrard, Vincent Meunier
A computationally efficient Green's function approach is developed to evaluate the optical properties of nanostructures using a GW formalism applied on top of a tight-binding and m…
