The Irish mathematician and physicist William Rowan Hamilton, who was born 220 years ago last month, is famous for carving some mathematical graffiti into Dublin's Broome Bridge in 1843.

This work, combining behavioural genetics and calcium imaging, provides evidence for a form of learning in Drosophila that derives solely from direct or (optogenetically induced) phantom experience of ...

A photonics research group co-led by Gregor Weihs of the University of Innsbruck has developed a new technique for generating multi-photon states from quantum dots that overcomes the limitations of ...

Chasing its ambition of adding 12 GW of renewables and firming capacity by 2035, the Australian Gas Light Company (AGL) Energy has acquired the Yadnarie solar and long-duration energy storage project ...

Excitons – bound pairs of electrons and electron hole – are quasiparticles that can arise in solids. While so-called “bright” excitons emit light and are therefore accessible, dark excitons are ...

The Photon Matrix can be used inside or outdoors, and is IP68 waterproof (meaning it can withstand being submerged to 1.5 m / 4.9 ft for 30 minutes) The Basic Edition model of the Photon Matrix has a ...

In a dark corner of a guest house in Helgoland, a diary by Werner Heisenberg has been discovered, describing how he developed quantum mechanics on the island 100 years ago. But in an even stranger ...

ABSTRACT: Third paper on the inverse relativity model, the first paper [1] included the splitting of total spacetime into positive and negative subspace-times, the second paper [2] included a ...

An advanced version of the famous double-slit experiment has directly measured a single photon in two places at once – or at least, that’s the claim made by a team of physicists who say these results ...

If photons possess more quantum states than expected, it would overhaul our understanding of all particle physics – and now physicists have identified a way to test this radical idea in an experiment.
