The interpretational problems of quantum mechanics are considered. The way in which the
standard Copenhagen interpretation of quantum mechanics deals with these problems is …

Interference effects produced by independent quantum sources are investigated, when the
state of the field is not describable as a simple mixture of coherent states. The results of …

By extending a Gedankenexperiment due to Elitzur and Vaidman and making some very
natural assumptions, we demonstrate that empty waves can manifest their reality in quantum …

The introduction by Dirac of a new aether model based on a stochastic covariant distribution
of subquantum motions (corresponding to a “vacuum state” alive with fluctuations and …

We present a new experimental set-up to detect the existence of de Broglie waves. Since it
uses only one, very weakened, incoherent source it escapes preceding objections and can …

Fundamental experiments on the dual nature of atomic entities (photons, electrons,
neutrons, etc.) can be interpreted in terms of “empty” waves not carrying energy and …

We present a reconstruction of the studies on the Foundations of Quantum Mechanics
carried out in Italy at the turn of the 1960s. Actually, they preceded the revival of the interest …

A simple formula relating the input and output quantum states of a beamsplitter is derived
and applied to the analysis of an interferometer with a photon duplicator along one arm. The …

The realist interpretations of quantum theory, proposed by de Broglie and by Bohm, are re-
examined and their differences, especially concerning many-particle systems and the …

If one starts from de Broglie's basic relativistic assumptions, ie, that all particles have an
intrinsic real internal vibration in their rest frame, ie, hv 0= m 0 c 2; that when they are at any …
