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 ...

... It is suggested in the general theory of relativity, which is the generally accepted theory of gravitation, that space-time is curved in a gravitational field. That is, the space-time scale changes from one point to another. What does this mean? What kind of physical difference exists between differ ...

Motion of a charged particle in a magnetic field
... Stokes’ theorem. This result shows that the" relative phase ∆ϕ is fixed by the factor q/! multiplied by the magnetic flux Φ = A B · d2 r enclosed by the loop.6 In the absence of a magnetic field, the flux vanishes, and there is no additional phase. However, if we allow the paths to enclose a region ...
