Photon transport in a dissipative chain of nonlinear cavities [PDF]

open access: yes, 2015
We analyze a chain of coupled nonlinear optical cavities driven by a coherent source of light localized at one end and subject to uniform dissipation. We characterize photon transport by studying the populations and the photon correlations as a function ...

Transport in electron-photon systems

open access: yesFrontiers of Physics, 2023
AbstractWe review the description and modeling of transport phenomena among the electron systems coupled via scalar or vector photons. It consists of three parts. The first part is about scalar photons, i.e., Coulomb interactions. The second part is with transverse photons described by vector potentials.

Verification and Analysis of the Problem-Dependent Multigroup Macroscopic Cross-Sections for Shielding Calculations

open access: yesEnergies, 2023
Multigroup constants are the foundation of neutron and photon transport problems, and the accuracy of multigroup cross-sections has a significant impact on shielding calculation.

Single-photon transport in a one dimentional waveguide coupling to a hybrid atom-optomechanical system [PDF]

open access: yes, 2013
We explore theoretically the single-photon transport in a single-mode waveguide that is coupled to a hybrid atom-optomechanical system in a strong optomechanical coupling regime.

Photon transport through a nanohole by a moving atom

open access: yesNew Journal of Physics, 2016
We have proposed and investigated for the first time an efficient way of photon transport through a subwavelength hole by a moving atom. The transfer mechanism is based on the reduction of the wave packet of a single photon due to its absorption by an ...

Photon albedo coefficients as functions of μ/Zeff parameter [PDF]

open access: yesNuclear Technology and Radiation Protection, 2013
This paper presents the results of the analyses of photon reflection from planar targets for normal photon incidence and for different shielding materials (water, concrete, aluminum, iron, and copper), in the range of the initial photon energies from ...

Dominant role of two-photon vertex in nonlinear response in two-dimensional Dirac systems

open access: yesnpj 2D Materials and Applications, 2021
We show that the standard concepts of nonlinear response to electromagnetic fields break down in two-dimensional Dirac systems, like graphene, in the quantum regime close to the Dirac point.

Monte Carlo electron/photon transport [PDF]

open access: yes, 2006
A review of nonplasma coupled electron/photon transport using the Monte Carlo method is presented. Remarks are mainly restricted to linerarized formalisms at electron energies from 1 keV to 1000 MeV. Applications involving pulse-height estimation, transport in external magnetic fields, and optical Cerenkov production are discussed to underscore the ...

Directing near-infrared photon transport with core@shell particles

open access: yesAIP Advances, 2020
Directing the propagation of near-infrared radiation is a major concern in improving the efficiency of solar cells and thermal insulators. A facile approach to scatter light in the near-infrared region without excessive heating is to embed compact layers
