Measurement of the Second-Order Polarizability of Silver Nanoparticles With Reference-Free Hyper-Rayleigh Scattering for Entangled Photon Pair Interaction

IEEE Photonics Journal, 2022
Two-photon interactions of entangled-photon pairs with metallic nanoparticles (NPs) can be enhanced by localized surface-plasmon resonance. Recently, we have described how the properties of this quantum light-matter interaction can be deduced from ...

Experimental results on photon-photon interactions at adone

Physics Letters B, 1979
Abstract Experimental results for the reactions e+e− → e+e− + X are presented for X = e+e−, μ+μ−, π+π− , ″'. A tagging technique has been used to detect final electrons and positrons. A QED test is performed and an upper limit of 20 keV is derived for the partial width Γ(η′ → γγ).

Quantum detector tomography of a time-multiplexed superconducting nanowire single-photon detector at telecom wavelengths [PDF]

, 2013
Superconducting nanowire single-photon detectors (SNSPDs) are widely used in telecom wavelength optical quantum information science applications. Quantum detector tomography allows the positive-operator-valued measure (POVM) of a single-photon detector ...

Photon-Photon Interaction in Glueball Production [PDF]

International Journal of Modern Physics: Conference Series, 2017
In the last years many exotic states have been identified in several colliders around the world. One of the exotic states provided in QCD is the glueball. Using a non-relativistic gluon bound-state model, we compute [Formula: see text], where [Formula: see text] is a pseudoscalar, tensor, or scalar digluon.

Photon-photon interaction mediated by a virtual photon in a nonlinear microcavity

, 2023
Interactions between single photons play a crucial role in both fundamental physics and quantum technologies. So far, only a few demonstrations of photon interactions have been accomplished using quantum emitters that are strongly coupled to optical ...

Detecting photon-photon interactions in a superconducting circuit

Physical Review B, 2015
A local interaction between photons can be engineered by coupling a nonlinear system to a transmission line. The required high impedance transmission line can be conveniently formed from a chain of Josephson junctions. The nonlinearity is generated by side-coupling this chain to a Cooper pair box.

Probing flavor-changing interactions in photon-photon collisions [PDF]

Physical Review D, 1998
We examine the subprocess $γγ\to t\bar{c}+\bar{t}c$ at electron-positron colliders in the two-Higgs-doublet model with flavor-changing scalar couplings, where all the one-loop contribuions are considered, and the results are applicable to the whole mass range of the weakly coupled Higgs bosons.

Photon–Atom Interactions: Intermediate Energies

, 2023
This chapter provides an overview of our understanding of photon–atom interactions involving soft x-rays, hard x-rays, and gamma-rays with “intermediate” photon energies roughly between 1 keV to 1 MeV (37 a.u. to 37 × 103 a.u.). These energies correspond
