Cosmic ray protons reveal new spectral structures at high energy

Observation of spectral structures in the cosmic ray proton flux from 50 GeV to 60 TeV with the calorimetric electronic telescope on the International Space Station. Credit: Waseda University Cosmic rays constitute high-energy protons and atomic nuclei that originate from stars (both within our galaxy and from other galaxies) and are accelerated by supernovae and … Read more

A computational perspective on the Nobel Prize

Contributions from the computational science community to Nobel laureates in chemistry and physics are at the heart of this month’s issue of Focus. Each year, as October approaches, the enthusiasm and speculation about the announcement of the new Nobel laureates spreads through the scientific community. By highlighting work that has had the “greatest benefit to … Read more

AI reduces a quantum physics problem of 100,000 equations to just four equations

Abstract illustration of quantum physics. Scientists trained a machine learning tool to capture the physics of electrons moving on a lattice using far fewer equations than are normally required, all without sacrificing.

Metastable states of floating crystals

Animation of the growth of a floating crystal from N = 3 to N = 19 particles. The particles are added one by one to the surface of the liquid under magnetic field. The capillary attractive forces are counterbalanced by the repulsive magnetic forces. The assembly shows a symmetry typical of atomic crystals. Credit: University … Read more
