"Prior to this work, we introduced a technique we called photon compensation in a Rydberg superatom, which we used to demonstrate the generation of atom-photon entanglement, and multiphoton ...

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 ...

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 ...

Researchers Baffled to Detect a Single Photon in More Than One Spot Simultaneously, Fueling the Multiverse Theory Physicists and Marvel aficionados worldwide are intrigued by multiverse theory. A ...

Traditional Feynman-diagram calculations also often use dimensional regularization, but normally the focus is just on the leading 1/ εn poles to carry out a renormalization programme.

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 ...

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 ...

This course gives an introduction to the quantum mechanics of many-body systems and the computational methods relevant for many-body problems in such diverse areas as atomic, molecular, solid-state ...

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 ...
