Description
Anton Gladyshev and colleagues present a new imaging framework in a 2026 study of atomic motion. Electron ptychography is a computer imaging method that can resolve single atoms. Their framework, called CAVIAR, looks for links between how neighboring atoms vibrate.
Tested on simulated data for a silicon grain boundary and real data for a boron nitride bicrystal, it found linked atomic movements of 10 to 20 picometers at room temperature. From just atomic masses and temperature, it also recovered vibration frequencies matching neutron scattering results. The authors offer it as a partner tool for studying atom dynamics.
