Depurification by Lorentz boosts
P. Kosinski, P. Maslanka
We consider a particle of half-integer spin which is nonrelativistic in the rest frame. Assuming the particle is completely polarized along third axis we calculate the Bloch vector…

Special relativity and reduced spin density matrices
Cezary Gonera, Piotr Kosinski, Pawel Maslanka
We derive the general formula for Lorentz-transformed spin density matrix. It is shown that an appropriate Lorentz transformation can prduce totally unpolarized state out of pure o…
