The topological properties of an object, associated with an integer called the topological
invariant, are global features that cannot change continuously but only through abrupt …

Atomtronics deals with matter-wave circuits of ultracold atoms manipulated through
magnetic or laser-generated guides with different shapes and intensities. In this way, new …

The research on cold-atom interferometers gathers a large community of about 50 groups
worldwide both in the academic and now in the industrial sectors. The interest in this sub …

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 …

We review the field of atom interferometer inertial sensors. We begin by reviewing the path
integral formulation of atom interferometers and then specialize the treatment to light-pulse …

We discuss the basic physics and instrumentation issues related to high-performance
physical and inertial sensors based on atomic spectroscopy. Recent work on atomic …

We reports improvements to our Sagnac effect matter-wave interferometer gyroscope. This
device now has a short-term rotation-rate sensitivity of 6× 10-10 rad s-1 over 1 s of …

A trapped-atom interferometer was demonstrated using gaseous Bose-Einstein
condensates coherently split by deforming an optical single-well potential into a double-well …

We have developed an atom interferometer providing a full inertial base. This device uses
two counterpropagating cold-atom clouds that are launched in strongly curved parabolic …

HeNe ring-laser gyros are standard sensors in inertial guidance; mirror reflectances now
reach 99.9999%. Present research instruments have an area of, a passive quality factor of …
