A new method in electron microscopy enables sub-20-picometer targeting of individual atoms without prior exposure, opening ...

To study the interactions between electrons in a material, physicists have come up with a number of tricks over the years.

Lattice QCD method suggests a simpler spectrum of exotic XYZ hadrons. ... The lattice box is tiny, with dimensions of 2 to 3 femtometers—nearly a million times smaller than a single atom.
