This paper presents an analysis of the double slit experience with light, by using concepts of the Feynman method of "sum of multiple paths" in quantum mechanics. The advantages of this formulation ...

Proton therapy is a type of external beam radiation therapy that delivers high dose radiation directly to cancer cells. Learn about its benefits and uses for breast cancer treatment.

The Nike Clogposite Photon Dust/Summit White and Multi-color/Off Noir colorways drop today, June 26, at 10 a.m. ET. Both shoes will be $145, but they could sell out fast.

GlueX The spectrometer at Jefferson Lab was used to study the behaviour of gluons within nuclei. (Courtesy: Jefferson Lab/Aileen Devlin) A new experiment has offered the clearest view yet of how ...

The development of practical two-photon absorption photoinitiators (TPA PIs) has been slow due to their complicated syntheses often reliant on expensive catalysts. These shortcomings have been a ...

We investigate the impact of reduced photon lifetime on the static and dynamic performance of high-speed, oxide-confined 850-nm vertical-cavity surface-emitting lasers (VCSELs). The photon lifetime is ...

However, photon-to-photon upconversion efficiencies of these devices are typically much lower than unity. Here we report an all-organic NIR-to-visible upconversion display with a photon-to-photon ...

Image deblurring in photon-limited conditions is ubiquitous in a variety of low-light applications such as photography, microscopy and astronomy. However, the presence of the photon shot noise due to ...
