On the derivation of the time-dependent equation of Schrödinger
Few have done more than Martin Gutzwiller to clarify the connection between classical time-
dependent motion and the time-independent states of quantum systems. Hence it seems …

On proper time and localization for the quantum relativistic electron
AJ Kálnay, E Mac Cotrina - Progress of Theoretical Physics, 1969 - academic.oup.com
A satisfactory proper time operator is found for Dirac's quantum relativistic electron. A self-
