Schematic showing how exotic particles known as excitons can “hop” between nickel atoms (grey dots) in nickel dihalide materials. The excitons are represented by the red and light-blue orbitals. Credit: Comin Laboratory. MIT physicists and colleagues report new insights into exotic particles key to a form of magnetism that has attracted growing interest because it

A prototype section of the proposed Cool Cooper Collider beam tunnel. Credit: Emilio Nanni/SLAC National Accelerator Laboratory Ever since the discovery of the Higgs boson in 2012, physicists have wanted to build new particle colliders to better understand the properties of that elusive particle and probe elementary particle physics at ever-higher energy scales. The trick
Isoscalar electromagnetic form factors at the lowest non-vanishing momentum (Q 2 ≈ 0.067 GeV2 ) on ensemble E300 as a function of the minimal source-sink separation entering the summation fit. Each blue point corresponds to a single fit starting at the value given on the horizontal axis. The associated weights in the average are represented
