Coherent Backscattering of Light with Nonlinear Atomic Scatterers [PDF]
Physical Review E, 2005 We study coherent backscattering of a monochromatic laser by a dilute gas of cold two-level atoms in the weakly nonlinear regime. The nonlinear response of the atoms results in a modification of both the average field propagation (nonlinear refractive ...

Phase-Insensitive Scattering of Terahertz Radiation [PDF]
Photonics, 2017 The nonlinear interaction between Near-Infrared (NIR) and Terahertz pulses is principally investigated as a means for the detection of radiation in the hardly accessible THz spectral region.

Emittance in nonlinear Thomson scattering
Physical Review Accelerators and Beams, 2022 Inverse Compton scattering sources are finding increasing use as intense sources of high-energy photons. When operated at high field strength, ponderomotive detuning of the scattered emission can lead to decreased source performance.

Scattering and inverse scattering for nonlinear quantum walks
Discrete & Continuous Dynamical Systems - A, 2018 We study large time behavior of quantum walks (QWs) with self-dependent (nonlinear) coin. In particular, we show scattering and derive the reproducing formula for inverse scattering in the weak nonlinear regime.

Surface Plasmon Resonance Dependent Third-Order Optical Nonlinearities of Silver Nanoplates
Photonics, 2021 A systematic study of the surface plasmon resonance (SPR)-dependent nonlinear optical response of Ag nanoplates is presented and discussed. The Ag nanoplates were synthesized using the well-known seed-mediated growth method.

Scattering Theory of Nonlinear Thermoelectric Transport [PDF]
Physical Review Letters, 2013 We investigate nonlinear transport properties of quantum conductors in response to both electrical and thermal driving forces. Within scattering approach, we determine the nonequilibrium screening potential of a generic mesoscopic system and find that its response is dictated by particle and entropic injectivities which describe the charge and entropy ...

Scattering for Stochastic Nonlinear Schrödinger Equations [PDF]
Communications in Mathematical Physics, 2019 We study the scattering behavior of global solutions to stochastic nonlinear Schr dinger equations with linear multiplicative noise. In the case where the quadratic variation of the noise is globally finite and the nonlinearity is defocusing,we prove that the solutions scatter at infinity in the pseudo-conformal space and in the energy space ...
