Even-harmonic generation through nonequilibrium steady-state symmetry breaking
Milad Jangjan, Arman Kashef, Siamak Pooyan +2
The paper shows that even-order high‑harmonic generation can appear in an inversion‑symmetric SSH chain when a nonequilibrium steady‑state current breaks the symmetry, linking tran…

Path integral quantization of the electromagnetic field in nonlinear dielectric materials
Arman Kashef, Oscar Perearnau Herrero, Alexander Szameit +2
We construct a quantum theory of light in nonlinear dielectric media with dispersion and absorption. We employ a mesoscopic model for the light-matter interaction that include a fo…
