... Consider two particles of mass m moving in one dimension. Particle 1 moves freely, while particle 2 experiences a harmonic potential V (x2 ) = 21 mω 2 x22 . The two particles interact via a delta function potential Vint (x12 ) = λδ(x12 ), with x12 ≡ x1 − x2 . Particle 2 starts in the ground state |ψ ...

... Gauge symmetry is not a symmetry. It is a fake, a redundancy introduced by hand to help us keep track of massless particles in quantum field theory. All physical predictions must be gauge-independent. In an ordinary quantum field theory without gravity, in flat spacetime, there two types of physical ...
