Quantum Coherence between States with Even and Odd Numbers of Electrons
... In 1952, Wick, Wightman, and Wigner [1] claimed that the coherent linear superpositions of states with even and odd numbers of fermions are incompatible with the Lorentz invariance and introduced the superselection rule, according to which such linear superpositions are physically impossible. In act ...
