Quantum Beam Science, 2022 The emission of characteristic lines after X-ray excitation is usually explained as the consequence of two independent and consecutive physical processes: the photoelectric ionization produced by incoming photons and the successive spontaneous atomic ...

Annals of Physics, 1961 Abstract A first order, momentum-configuration space transport equation for photons is derived for low energy (nonrelativistic) systems. The derivation is first order in the sense that the transition probabilities characterizing photon scattering emission and absorption are computed only to the first nonvanishing order by conventional perturbation ...

On model-based hyperspectral imaging
Current Directions in Biomedical Engineering, 2022 Several contributions are presented to aid the analysis of hyperspectral images by utilizing appropriate optical models. The algorithms are described by means of the perfusion of human skin and a corresponding two-layer tissue model.

Transport in Sawtooth photonic lattices [PDF]
Optics Letters, 2016 We investigate, theoretically and experimentally, a photonic realization of a Sawtooth lattice. This special lattice exhibits two spectral bands, with one of them experiencing a complete collapse to a highly degenerate flat band for a special set of inter-site coupling constants.

Experimental Proof of a Solar-Powered Heat Pump System for Soil Thermal Stabilization
Energies, 2022 We suggested earlier a new sustainable method for permafrost thermal stabilization that combines passive screening of solar radiation and precipitation with active solar-powered cooling of the near-surface soil layer thus preventing heat penetration in ...

Fiber transport of spatially entangled photons [PDF]
SPIE Proceedings, 2011 Entanglement in the spatial degrees of freedom of photons is an interesting resource for quantum information. For practical distribution of such entangled photons it is desireable to use an optical fiber, which in this case has to support multiple transverse modes.

A laser–plasma platform for photon–photon physics: the two photon Breit–Wheeler process
New Journal of Physics, 2021 We describe a laser–plasma platform for photon–photon collision experiments to measure fundamental quantum electrodynamic processes. As an example we describe using this platform to attempt to observe the linear Breit–Wheeler process.
