Photonic quantum transport in a nonlinear optical fiber [PDF]

EPL (Europhysics Letters), 2011
We theoretically study the transmission of few-photon quantum fields through a strongly nonlinear optical medium. We develop a general approach to investigate non-equilibrium quantum transport of bosonic fields through a finite-size nonlinear medium and apply it to a recently demonstrated experimental system where cold atoms are loaded in a hollow-core

Scattering theory of photon-assisted electron transport [PDF]

Physical Review B, 1998
The scattering matrix approach to phase-coherent transport is generalized to nonlinear ac-transport. In photon-assisted electron transport it is often only the dc-component of the current that is of experimental interest. But ac-currents at all frequencies exist independently of whether they are measured or not.

A Practical Noise2Noise Denoising Pipeline for High‐Throughput Raman Spectroscopy

Advanced Engineering Materials, EarlyView.
A lightweight and reproducible denoising pipeline for high‐throughput Raman spectroscopy is introduced, based on a 1D convolutional autoencoder trained with a Noise2Noise strategy. Using only repeated short‐exposure acquisitions, the method suppresses stochastic noise without reference spectra, enabling reliable spectral reconstruction while preserving

Impact of skin pores on photon transport in near–infrared optical tissue imaging

Journal of the European Optical Society-Rapid Publications
Near-infrared optical tissue imaging is sensitive to both the optical properties of biological media and their microstructural geometry. While macroscopic tissue characteristics are well studied, the quantitative impact of skin pores on photon ...

Design and Analysis of Compression–Torsion Coupling Metamaterials Using the Golden Section Method

Advanced Engineering Materials, EarlyView.
A novel compression–torsion metamaterial is engineered using inclined rods and symmetry breaking. To optimize its torsional performance, the golden section method is employed. The mechanical response of the metamaterial is validated through both numerical analysis and experimental validation.

Casimir effect in kinetic theory

New Journal of Physics, 2022
We study Casimir effect in equilibrium and non-equilibrium photon gas in the frame of quantum kinetic theory for U (1) gauge field. We derive first the transport, constraint and gauge fixing equations for the photon number distribution from Maxwell’s ...

Photonic Newton’s Cradle for Remote Energy Transport [PDF]

Physical Review Applied, 2019
Energy transport is of central importance in understanding a wide variety of transitions of physical states in nature. Recently, the coherence and noise have been identified for their existence and key roles in energy transport processes, for instance, in a photosynthesis complex, DNA, and odor sensing etc, of which one may have to reveal the inner ...
