First observation of antimatter wave interference
Simone Sala    Dottorato di Ricerca in Fisica del Dip. di Fisica
"Double-slit-like quantum interference with single matter particles (electrons) was a highly sought-after result, finally carried out in 1976 and voted as the “most beautiful experiment in physics” by Physics World readers in 2002.
Here we present the first observation of a quantum wave interference with single antimatter particles, positrons, by using a period-magnifying Talbot-Lau interferometer based on material diffraction gratings."
