Relaxed multi-marginal costs and quantization effects
Guy Bouchitté, Giuseppe Buttazzo, Thierry Champion +1
We propose a duality theory for multi-marginal repulsive cost that appear in optimal transport problems arising in Density Functional Theory. The related optimization problems invo…

Dissociating limit in Density Functional Theory with Coulomb optimal transport cost
Guy Bouchitté, Giuseppe Buttazzo, Thierry Champion +1
In the framework of Density Functional Theory with Strongly Correlated Electrons we consider the so called bond dissociating limit for the energy of an aggregate of atoms. We show…

Homogenization of membrane and pillar photonic crystals
D. Felbacq, G. Bouchitté, A. Moreau
We study wave propagation and diffraction in a bidimensional photonic crystal with finite height, in case where the wavelength is large with respect to the period of the structure.…
