The photon position operator (non-commuting) and its string-like eigenstates
Grzegorz M. Koczan
The paper provides three main definitions of the Cartesian photon position operator based on: boost generator, the transversality condition and the helicity operator. In each case,…

Relative binary and ternary 4D velocities in the Special Relativity in terms of manifestly covariant Lorentz transformation
Grzegorz M. Koczan
Zbigniew Oziewicz was a pioneer of the 4D space-time approach to covariant relative velocities. In the 1980s (according to private correspondence) he discovered two types of 4D rel…

Relativistic relative velocities and relativistic acceleration
Grzegorz M. Koczan
It turns out that the standard application of the four-vector SR formalism does not include the concept of relative velocity. Only the absolute velocity is described by the four-ve…
