SUMMARY: (...): Discontinuous Galerkin methods for the numerical modeling o
 f  nanoscale light/matter interactions
DESCRIPTION:: The numerical modeling of nanoscale light/matter interactions
  requires to solve the system of Maxwell equations possibly coupled to app
 ropriate models of physical dispersion such as the Drude and Drude-Lorentz
  models. When this modeling is undertaken by assuming a time-domain regime
 \, the simulation technique of choice is the Finite Difference Time-Domain
  (FDTD) method [1].  In this method\, the whole computational domain is di
 scretized using   a structured (Cartesian) grid and regular stencils are u
 sed to discretize the differential terms of Maxwell’s equations. The sim
 plicity of the method together with its computational efficiency has drive
 n its popularity in the computational electromagnetics community. However\
 , for nanophotonic applications\, the space and time scales\, in addition 
 to   the geometrical characteristics of the considered nanostructures (or 
 structured layouts of the latter)\, are particularly challenging for an ac
 curate and efficient application of the FDTD method.  In this talk\, we wi
 ll report on recent contributions on the design\, analysis and development
  of high order DGTD (Discontinuous Galerkin Time-Domain) methods [2] for t
 he numerical treatment of nanoscale light/matter interactions in the time-
 domain regime. [1] A. Taflove and S. C. Hagness\, Computational Electrodyn
