Invited Speaker / Conférencier invité
Récents progrès dans les techniques de fabrication de microcavités à semi-conducteurs ont permis d’observer des nouveaux états propres issus du couplage fort entre un champ photonique fortement confiné et des excitons de puits quantiques. Ces états, appelés exciton-polaritons, ont un caractère mixte lumière-matière qui leur confère des propriétés très particulières. Notamment, leur faible...

Recently, several papers reported the discovery of giant permittivity and low dielectric loss in (Nb+In) co-doped TiO$_2$. A series of tests was performed which included the measurement of the frequency dependence of the dielectric permittivity and ac conductivity of co-doped (Nb+In)TiO$_2$ as a function of electrode type, sample thickness and temperature. The data suggest that the...

Weyl semimetals are three dimensional crystals that contain topologically protected Dirac fermions in the electronic band structure.
These materials display an array of unusual transport and optical properties, which can be traced to the emergence of an axion term in Maxwell's equations.
Predicted four decades ago in the context of high energy physics, the axion has remained experimentally...

We present a mapping of a two-dimensional system of interacting bosons in a strong perpendicular magnetic eld to an equivalent system of interacting bosons on the square lattice in the absence of the eld. The mapping utilizes a magnetic Bloch and the corresponding magnetic Wannier singleparticle basis in the lowest Landau level. By construction, the ground states of the resulting model of...
