Two-electron Interference
... possible. For a single particle, the interference is between the amplitudes of the particle’s wave function, whereas the interference between two particles is a direct result of quantum exchange statistics. Such interference is observed only in the joint probability of finding the particles in tw ...

... This corresponds physically to a positive point charge at the origin with one unit of elementary charge, and a finite cloud of negative charge that decays exponentially, but contains a total charge of one unit of elementary charge. From a time-averaged perspective then, hydrogen in the ground state ...
