The technique of stimulated Raman adiabatic passage (STIRAP), which allows efficient and
selective population transfer between quantum states without suffering loss due to …

Interference with atomic and molecular matter waves is a rich branch of atomic physics and
quantum optics. It started with atom diffraction from crystal surfaces and the separated …

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 …

Many branches of contemporary physics require atoms or molecules prepared in specified
quantum states—not only for traditional studies of state-to-state collision dynamics, isotope …

Stimulated adiabatic passage utilizes radiation pulses to efficiently and selectively transfer
population between quantum states, via an intermediate state that is normally decaying. In …

The influence of the geometric phase, in particular the Berry phase, on an entangled spin-1
2 system is studied. We discuss in detail the case, where the geometric phase is generated …

In an open system, the geometric phase should be described by a distribution. We show that
a geometric phase distribution for open system dynamics is in general ambiguous, but the …

Theoretical and experimental studies of Berry and Pancharatnam phases are reviewed.
Basic elements of differential geometry necessary for understanding the topological nature …

We propose a scheme for measuring the Berry phase in the vibrational degree of freedom of
a trapped ion. Starting from the ion in a vibrational coherent state we show how to reverse …

We propose a possible scheme for generating spin-J geometric phases using a coupled two-
mode Bose-Einstein condensate (BEC). First we show how to observe the standard Berry …
