The measurements showed that the absorption corresponds to single photon traveling in either one or another beam. The results of our measurements and of single photon interference experiments, ...

One such state, first proposed by Nobel laureate Eugene Wigner, is the Wigner crystal—a structured electron arrangement ... them into a crystal-like structure. Here, we identified flakes of ...
