Considerations on the introduction of a fundamental interval of time (the so-called chronon)
in order to solve some difficulties in the theory of elementary particles are not new. In …

The letter extends the author's previous considerations on classical radiating electron to
quantum mechanics. As a first approximate step the possibility is considered of introducing …

In this paper an organic exposition is given of a new quantum theory of the electron based
on the introduction of the chronon in physics. Such a theory is developed essentially without …

In the last years we have (1) reconsidered and improved in several points a relativistic
theory of the classical electron already proposed by us many years ago (3). Such a theory is …

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 …

Abstract “Time” as an observable of a physical system is to be understood with reference to
the evolution of some nonstationary quantity. Thus, any observable “time” is the time of …

The space-time approach to quantum electrodynamics, as has been developed by
Feynman, seems to offer a very attractive and useful idea to this domain of physics. His …

A satisfactory proper time operator is found for Dirac's quantum relativistic electron. A self-
consistent scheme is developed in which this operator and Beck's proper time derivative …

The so-called time operator in quantum mechanics which may be regarded as a coordinate
conjugate to Hamiltonian operator is studied. Three typical examples of the time operators in …

The introduction of a fundamental interval of time, the so-called chronon, in the classical (1)
and quantum (2) theory of the electron has made possible to overcome some considerable …
