ALICE Collaboration’s Post

The ultra-high energy lead beams at the #LHC act as photon sources, with the photons from the incoming nuclei interacting strongly with the other nucleus. This gives rise to a quantum interference at the femtometre scale which has been measured by the @alice_experiment, akin to that of the famous double-slit experiment (a femtometre is a quadrillionth of a metre)!

【Quantum Unruh Effect on Radiation of Black Holes】 Full article: https://lnkd.in/g38RJxRz (Authored by Tianxi Zhang, from Alabama A & M University, USA.) This study investigates the quantum Unruh effect on radiation of gravitational objects including #black_holes and shows that the emission power of Unruh radiation from a gravitational object including a black hole should be calculated in terms of the rate of increase of the total Unruh radiation energy outside the object. #Gravitation #Quantum_Field_Theory #Blackbody_Radiation

https://lnkd.in/e4NPqWuv Time for some new resource - in two bit size parts. The first is a new article in our maths / physics section of the website "Criticality and delayed neutrons". The article concepts are fairly easy to understand and you can go into the maths as much as you like (quite over my head mostly!). However, the resource is illustrated by a part 2 announcement later involving a criticality simulation widget - stay tuned for that! The resource has been created for us by the ever excellent Dr Chris Robbins of Grallator. Chris is fabulous to work with and is helping Ionactive to provide unique educational radiation protection resources, much of which is shared on our public website. From the very beginning the Ionactive website has provided both commercial services and freely available radiation safety resource. So dig in for now and have a play with he widget when released later! (which is now, the interactive widget can be found here : https://lnkd.in/e9jnS5un )

A first definitive demonstration of nonthermal particle acceleration in magnetorotational turbulence by Ingrid Fadelli A first definitive demonstration of nonthermal particle acceleration in magnetorotational turbulence Spatial distribution of plasma current density during nonlinear, steady-state magnetorotational turbulence in the accretion flow around a supermassive black hole. In this turbulence, charged particles (electrons and ions) can be efficiently accelerated to very high (even relativistic) energies. Accelerated electrons can reach energies high enough to activate radiative processes, resulting in the emission of light that can be ultimately observed from Earth. Anthony: Neat

Quantum acoustics unlocks another mystery of strange metals! In our work published in the prestigious Proceedings of the National Academy of Sciences (PNAS), we show that the charge carriers in strange metals exhibit quantum diffusion, leading to Planckian resistivity. #quantum #condensedmatter #pnas https://lnkd.in/di4Q-TiC

To learn about science history always fascinating.

There are three massless particles: the gluon, the photon, and the graviton. However, the graviton is hypothetical at this point. Photons are the particles that make up light. Gluons are the particles that hold quarks together to form neutrons and protons, and hold neutrons and protons together to form atomic nuclei. As massless particles, they must always travel at the speed of light in vacuum, in all reference frames. They can exist despite having no mass because they have energy and momentum.
