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…

Efficient extraction of resonant states in systems with defects
Ivan Duchemin, Luigi Genovese, Eloïse Letournel +2
We introduce a new numerical method to compute resonances induced by localized defects in crystals. This method solves an integral equation in the defect region to compute analytic…
