Heisenberg's uncertainty principle is usually taken to express a limitation of operational
possibilities imposed by quantum mechanics. Here we demonstrate that the full content of …

Atom optics refers to techniques to manipulate the trajectories and exploit the wave
properties of neutral atoms. In 1929 0. Stern and colleagues [1—3] laid the first stones, by …

Although there are many textbooks that deal with the formal apparatus of quantum
mechanics (QM) and its application to standard problems, none take into account the …

The quantum interference of de Broglie matter waves is probably one of the most startling
and fundamental aspects of quantum mechanics. It continues to tax our imaginations and …

In the 1950's interest arose in the science-fiction idea of “antigravity”. This concept was a
speculation that matter and antimatter would repel each other in ordinary tensor …

This report deals with the quantum field theory of particle oscillations in vacuum. We first
review the various controversies regarding quantum-mechanical derivations of the …

Quantum mechanics is generally regarded as the physical theory that is our best candidate
for a fundamental and universal description of the physical world. The conceptual framework …

The notion of uncertainty in the description of a physical system has assumed prodigious
importance in the development of quantum theory. Overcoming the early misunderstanding …

A Sagnac experiment with electron waves in vacuum is reported. The phase shift caused by
rotation of an electron biprism interferometer placed on a turntable has been measured. It …

The neutron interferometer is a unique instrument that allows one to construct a neutron
wave packet of macroscopic size, divide it into two components separated by centimeters …
