Spin operator in the Dirac theory
Pawel Caban, Jakub Rembieliński, Marta Włodarczyk
We find all spin operators for a Dirac particle satisfying the following very general conditions: (i) spin does not convert positive (negative) energy states into negative (positiv…
Absolute clock synchronisation and special relativity paradoxes
Jacek Ciborowski, Marta Wlodarczyk
Solving special relativity paradoxes requires rigorous analysis of event timing, due to relative simultaneity in consequence of the Lorentz transformation. Since clock synchronisat…
Relativistic spin operator and Dirac equation
Paweł Caban, Jakub Rembieliński, Marta Włodarczyk
We give a direct link between description of Dirac particles in the abstract framework of unitary representation of the Poincaré group and description with the help of the Dirac eq…
"Meta" relativity: Against special relativity?
Jakub Rembielinski, Marta Wlodarczyk
We introduce a Lorentz-covariant description of tachyons, free of inconsistencies. Our approach is based on an appropriate extension of the special relativity beyond the light barr…
Einstein-Podolsky-Rosen correlations in a hybrid system
Paweł Caban, Jakub Rembieliński, Piotr Witas +1
We calculate the relativistic correlation function for a hybrid system of a photon and a Dirac-particle. Such a system can be produced in decay of another spin-1/2 fermion. We show…
Relativistic Einstein-Podolsky-Rosen correlations for vector and tensor states
Paweł Caban, Jakub Rembieliński, Marta Włodarczyk
We calculate and investigate the relativistic correlation function for bipartite systems of spin-1/2 in vector and spin-1 particles in tensor states. We show that the relativistic…
