Photon–photon scattering: a tutorial [PDF]

Canadian Journal of Physics, 2012
Long-established results for low-energy photon–photon scattering, γγ → γγ, have recently been questioned. We analyze that claim and demonstrate that it is inconsistent with experience. We demonstrate that the mistake originates from an erroneous manipulation of divergent integrals and discuss the connection with another recent claim about the Higgs ...

Electron-photon interaction in quantum dots : spin and entanglement [PDF]

, 2005
The interaction of electrons and photons lies at the heart of quantum physics. The most notable phenomena which are described by quantum physics but which obviously invalidate a classical description of the electromagnetic field - the photoelectric ...

Effect of dysprosium on the radiation-shielding features of SiO2–PbO–B2O3 glasses

Open Physics, 2023
In a variety of applications using ionizing radiation, it is essential to ensure the safety of both individuals and equipment. To this end, excellent radiation shielding materials, including glasses and rare earth elements, such as Dy2O3, are currently ...

Overcoming phonon-induced dephasing for indistinguishable photon sources [PDF]

, 2012
Reliable single photon sources constitute the basis of schemes for quantum communication and measurement based quantum computing. Solid state single photon sources based on quantum dots are convenient and versatile but the electronic transitions that ...

High energy photon-photon collisions [PDF]

Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 1995
The collisions of high energy photons produced at an electron-positron collider provide a comprehensive laboratory for testing QCD, electroweak interactions, and extensions of the Standard Model. The luminosity and energy of the colliding photons produced by back-scattering laser beams is expected to be comparable to that of the primary $e^+e ...

Photonic circuits for generating modal, spectral, and polarization entanglement [PDF]

, 2010
We consider the design of photonic circuits that make use of Ti:LiNbO(3) diffused channel waveguides to generate photons with various combinations of modal, spectral, and polarization entanglement.

Learning cellular morphology with neural networks

Nature Communications, 2019
Volume electron microscopy data of brain tissue can tell us much about neural circuits, but increasingly large data sets demand automation of analysis. Here, the authors introduce cellular morphology neural networks and successfully automate a range of ...

Compact coupler designs for quantum optical circuits produced by direct UV writing [PDF]

, 2009
Integrated planar lightwave circuits (PLCs) provide a promising route to small-scale quantum optical networks [1]. Recent work on quantum logic gates using silica-based PLCs has highlighted the opportunities afforded by the ability to coherently ...
