Kerr coefficients of plasma resonances in Josephson junction chains
, 2015 We present an experimental and theoretical analysis of the self- and cross-Kerr effect of extended plasma resonances in Josephson junction chains. We calculate the Kerr coefficients by deriving and diagonalizing the Hamiltonian of a linear circuit model ...

Saturation of the All-Optical Kerr Effect
Physical Review Letters, 2011 Saturation of the intensity dependence of the refractive index is directly computed from ionization rates via a Kramers-Kronig transform. The linear intensity dependence and its dispersion are found in excellent agreement with complete quantum mechanical orbital computations.

Measuring the nonlinear refractive index of graphene using the optical Kerr effect method. [PDF]
Optics Letters, 2016 By means of the ultrafast optical Kerr effect method coupled to optical heterodyne detection (OHD-OKE), we characterize the third-order nonlinear response of graphene and compare it to experimental values obtained by the Z-scan method on the same samples.

Research Paper: Polar Kerr Effect in a Magnetized Plasma Layer [PDF]
فیزیک کاربردی ایرانIn this paper, we investigate the polarization rotation of an electromagnetic beam reflected from a magnetized plasma layer. To this end, using a matrix method based on Maxwell’s equations, we derive the reflection coefficient and the polarization ...

Tailoring optical nonlinearities via the Purcell effect
, 2007 We predict that the effective nonlinear optical susceptibility can be tailored using the Purcell effect. While this is a general physical principle that applies to a wide variety of nonlinearities, we specifically investigate the Kerr nonlinearity.
