Variable Mass and the Noisy Feynman Propagator in Scalar Fields
Allan Tameshtit
We utilize a mass independent Klein-Gordon equation that is first order in a variable that plays the role of time, the approach taken in parametric time formulations. Using concept…
The explicit form of the unitary representation of the Poincaré group for vector-valued wave functions (massive and massless), with applications to photon's localization and position operators
Arkadiusz Jadczyk
We geometrically derive the explicit form of the Unitary representation of the Poincare group and use it to apply speed-of-light boosts to simple polarization basis to end up with…
Sign of the Feynman Propagator and Irreversibility
Allan Tameshtit
For the interacting Feynman propagator of scalar electrodynamics, we show that the sign property, , hinges on the reversib…
Time of arrival operator in the momentum space
A. M. Schlichtinger, A. Jadczyk
It is shown that in presence of certain external fields a well defined self-adjoint time operator exists, satisfying the standard canonical commutation relations with the Hamiltoni…
