Manifestation of the Purcell Effect in Current Transport through a Dot–Cavity–QED System

open access: yesNanomaterials, 2019
We study the transport properties of a wire-dot system coupled to a cavity and a photon reservoir. The system is considered to be microstructured from a two-dimensional electron gas in a GaAs heterostructure.

Coexisting spin and Rabi oscillations at intermediate time regimes in electron transport through a photon cavity

open access: yesBeilstein Journal of Nanotechnology, 2019
In this work, we theoretically model the time-dependent transport through an asymmetric double quantum dot etched in a two-dimensional wire embedded in a far-infrared (FIR) photon cavity.

Thermoelectric Inversion in a Resonant Quantum Dot-Cavity System in the Steady-State Regime

open access: yesNanomaterials, 2019
We theoretically investigate thermoelectric effects in a quantum dot system under the influence of a linearly polarized photon field confined to a 3D cavity.

Major and Minor Contributions to X-ray Characteristic Lines in the Framework of the Boltzmann Transport Equation

open access: yesQuantum 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 ...

On model-based hyperspectral imaging

open access: yesCurrent 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.

Experimental Proof of a Solar-Powered Heat Pump System for Soil Thermal Stabilization

open access: yesEnergies, 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 ...

A laser–plasma platform for photon–photon physics: the two photon Breit–Wheeler process

open access: yesNew 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.

Parallelized Monte Carlo Photon Transport Simulations for Arbitrary Multi-Angle Wide-Field Illumination in Optoacoustic Imaging

open access: yesFrontiers in Physics, 2020
Optoacoustic imaging (OAI) or photoacoustic imaging can resolve the distribution of tissue chromophores and optical contrast agents deep inside tissue from the optoacoustic detection with multi-spectral illumination.

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.
