Photon transport in binary photonic lattices

open access: yesPhysica Scripta, 2013
We present a review on the mathematical methods used to theoretically study classical propagation and quantum transport in arrays of coupled photonic waveguides. We focus on analysing two types of binary photonic lattices where self-energies or couplings are alternated.

Photon bubble turbulence in cold atom gases

open access: yesNature Communications, 2021
Photon bubble turbulence is an astrophysical phenomenon involving radiation transport. Here, the authors report analogous behavior in ultracold gas by observing signatures of photon bubble instabilities in Rb atoms trapped in a MOT.

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 ...

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.

Geometric Potential and Transport in Photonic Topological Crystals [PDF]

open access: yesPhysical Review Letters, 2010
We report on the experimental realization of an optical analogue of a quantum geometric potential for light wave packets constrained on thin dielectric guiding layers fabricated in silica by the femtosecond laser writing technology. We further demonstrate the optical version of a topological crystal, with the observation of Bloch oscillations and Zener

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.

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.
