Characterizing the topological properties of one-dimensional non-hermitian systems without the Berry-Zak phase
Didier Felbacq, Emmanuel Rousseau
A new method is proposed to predict the topological properties of one-dimensional periodic structures in wave physics, including quantum mechanics. From Bloch waves, a unique compl…
A single layer representation of the scattered field for multiple scattering problems
Didier Felbacq, Anthony Gourdin, Emmanuel Rousseau
The scattering of scalar waves by a set of scatterers is considered. It is proven that the scattered field can be represented as an integral supported by any smooth surface enclosi…
On the concept of a generalized law of refraction: A phenomenological model The Article and the Supporting Informations
Emmanuel Rousseau, Didier Felbacq
This paper presents investigations on the generalized laws of refraction and reflection for metasurfaces made of diffractive elements. It introduces a phenomenological model that r…
Global properties of the growth index: mathematical aspects and physical relevance
R. Calderon, D. Felbacq, R. Gannouji +2
We analyze the global behaviour of the growth index of cosmic inhomogeneities in an isotropic homogeneous universe filled by cold non-relativistic matter and dark energy (DE) with…
Global properties of the growth index of matter inhomogeneities in the universe
R. Calderon, D. Felbacq, R. Gannouji +2
We perform here a global analysis of the growth index behaviour from deep in the matter era till the far future. For a given cosmological model in GR or in modified gravity, th…
Rigorous asymptotic study of the screened electrostatic potential in a thin dielectric slab
Didier Felbacq, Emmanuel Rousseau
The screened Coulomb potential plays a crucial role in the binding energies of excitons in a thin dielectric slab. The asymptotic behavior of this potential is studied when the thi…
