Rewinding Protocol for Reversing Certain Quantum Processes

In the world around us processes appear to follow a certain time-direction: dandelions eventually turn into blowballs. However, the quantum realm does not play by the same rules.

New Method to Create High-Energy “Quantum Light” to Explore Properties at Atomic Scale

The scientists, from the University of Cambridge, together with colleagues from Austria, the US, and Israel formulated a theory illustrating a new state of light, which has exploitable quantum properties across a wide range of frequencies, nearly as high as X-ray frequencies.

An Unmatched View of the Faint Intracluster Light in Galaxy Clusters

A new study, completely carried out by scientists at the Instituto de Astrofísica de Canarias (IAC), has come up with the most comprehensive analysis thus far of the intracluster light (ICL)—the diffuse and faint light—discharged by stars in galaxy clusters that are not gravitationally connected to any galaxy.
