    "abstract": "We derive the general formula for Lorentz-transformed spin density matrix. It\nis shown that an appropriate Lorentz transformation can prduce totally\nunpolarized state out of pure one. Further properties, as depurification by an\narbitrary Lorentz boost and its relation to the localization properties are\nalso discussed.",
