Nonlinear quantum noise polarization in macroscopic nonlinear QED
Arman Kashef, Stefan Scheel, Marco Ornigotti
We construct a quantum theory of light in nonlinearly responding materials with dispersion and absorption and, in particular, show the emergence of non-Gaussian noise associated wi…
Even-harmonic generation through nonequilibrium steady-state symmetry breaking
Milad Jangjan, Arman Kashef, Siamak Pooyan +2
High-harmonic generation (HHG) in inversion-symmetric systems is typically restricted to odd harmonics by symmetry. Here, we show that this selection rule can be broken without mod…
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…
Entanglement degradation under local dissipative Landau-Zener noise
Melika Babakan, Arman Kashef, Laleh Memarzadeh
We study entanglement degradation when noise on one share of an entangled pair is described by the dissipative Landau-Zener model. We show that spin-coupling direction to the envir…
