Deformation mechanisms in a superelastic NiTi alloy: An in-situ high resolution digital image correlation study

open access: yesMaterials & Design, 2020
An in-situ high resolution digital image correlation investigation during uniaxial tensile deformation reveals the recoverable and the non-recoverable strain mechanisms in a Ni51Ti49 alloy with a mean grain size of 35 μm. Recoverable strain is due to the

Single-photon microwave photonics

open access: yesScience Bulletin, 2022
With the rapid development of microwave photonics technology, high-speed processing and ultra-weak signal detection capability have become the main bottlenecks in many applications. Thanks to the ultra-weak signal detection capability and the extremely low timing jitter properties of single-photon detectors, the combination of single-photon detection ...

VIRTUAL PHOTON–PHOTON SCATTERING [PDF]

open access: yesInternational Journal of Modern Physics: Conference Series, 2014
Based on analyticity, unitarity, and Lorentz invariance the contribution from hadronic vacuum polarization to the anomalous magnetic moment of the muon is directly related to the cross section of e + e − → hadrons .

Photoinactivation of Escherichia coli using five photosensitizers and the same number of photons

open access: yesJournal of Innovative Optical Health Sciences, 2022
Bacterial resistance is today a matter of great medical concern, so it is urgent to investigate alternatives to alleviate it. Photodynamic inactivation (PDI) is a method that has been endorsed to inactivate different pathogens, including bacteria, fungi ...

Photon-photon interaction in a photon gas [PDF]

open access: yesEurophysics Letters (EPL), 2000
Using the effective Lagrangian for the low energy photon-photon interaction the lowest order photon self energy at finite temperature and in non-equilibrium is calculated within the real time formalism. The Debye mass, the dispersion relation, the dielectric tensor, and the velocity of light following from the photon self energy are discussed.

PHOTON-PHOTON INTERACTIONS [PDF]

open access: yesNuclear Physics A, 1981
Abstract A brief summary of the present status of photon-photon interactions is presented. Stress is placed on the use of two-photon collisions to test present ideas on the quark constituents of hadrons and on the theory of strong interactions.
