Proper time derivatives in quantum mechanics
Juan P. Aparicio, Fabian H. Gaioli, Edgardo T. Garcia Alvarez
Several quantum proper time derivatives are obtained from the Beck one in the usual framework of relativistic quantum mechanics (spin 1/2 case). The ``scalar Hamiltonians'' of thes…
Some remarks about intrinsic parity in Ryder's derivation of the Dirac equation
Fabian H. Gaioli, Edgardo T. Garcia Alvarez
This work is a comment on Ryder's derivation of the Dirac equation, with emphasis on the physical contents of this equation: the notion of particles and antiparticles according to…
Feynman's proper time approach to QED
Edgardo T. Garcia Alvarez, Fabian H. Gaioli
The genesis of Feynman's original approach to QED is reviewed. The main ideas of his original presentation at the Pocono Conference are discussed and compared with the ones involve…
Classical and quantum theories of spin
Fabian H. Gaioli, Edgardo T. Garcia Alvarez
A great effort has been devoted to formulate a classical relativistic theory of spin compatible with quantum relativistic wave equations. The main difficulty in order to connect cl…
