Einstein-Podolsky-Rosen-Bohm experiment with relativistic massive particles
Marek Czachor
The EPRB experiment with massive partcles can be formulated if one defines spin in a relativistic way. Two versions are discussed: The one using the spin operator defined via the r…
Generalized quantum measurements and local realism
Marek Zukowski, Ryszard Horodecki, Michal Horodecki +1
The structure of a local hidden variable model for experiments involving sequences of measurements rigorously is analyzed. Constraints imposed by local realism on the conditional p…
Separability of Mixed States: Necessary and Sufficient Conditions
Michal Horodecki, Pawel Horodecki, Ryszard Horodecki
We provide necessary and sufficient conditions for separability of mixed states. As a result we obtain a simple criterion of separability for and systems. Her…
Teleportation, Bell's Inequalities and Inseparability
Ryszard Horodecki, Michal Horodecki, Pawel Horodecki
Relations between teleportation, Bell's inequalities and inseparability are investigated. It is shown that any mixed two spin- state which violates the Bell-CHSH inequalit…
Manifestly Covariant Approach to Bargmann-Wigner Fields (I): Generalized scalar products and Wigner states
Marek Czachor
Manifestly covariant formalism for Bargmann-Wigner fields is developed. It is shown that there exists some freedom in the choice of the form of the Bargmann-Wigner scalar product:…
Nambu-Type Generalization of the Dirac Equation
Marek Czachor
Nonlinear generalization of the Dirac equation extending the standard paradigm of nonlinear Hamiltonians is discussed. ``Faster-than-light telegraphs" are absent for all theories f…
