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…

Fundamental solution method applied to time evolution of two energy level systems: exact and adiabatic limit results
Stefan Giller, Cezary Gonera
A method of fundamental solutions has been used to investigate transitions in two energy level systems with no level crossing in a real time. Compact formulas for transition probab…
