Special Issue Information

Dear Colleagues,

Wave–particle duality is a bedrock of our highly successful quantum theory of nature. While the notion of an atom wave has been part of the established structure of quantum mechanics for a century, it was only in the 1990s that the first atom interferometers and dilute gas Bose–Einstein condensates were demonstrated. These two key experimental milestones provided us with direct access to atomic waves and their manipulation, consequently opening up a range of new fundamental sciences and applications.

Interferometry with de Broglie waves has been used for inertial sensing of accelerations and rotations, for measurements of gravity and its gradient, for precision measurements of atomic interactions, and for tests of fundamental theories such as quantum electrodynamics and the equivalence principle. Laser-cooled atoms have been a principal source of de Broglie waves for such precision atom interferometry.

Dilute gas Bose–Einstein condensates (BECs) represent the ultimate de Broglie atom wave; they are sometimes referred to as “atom lasers” since they possess coherence properties similar to their optical wave counterpart. After initial demonstrations of interference phenomena with BECs, several research groups have developed BEC-based atom interferometric applications, exploiting advantages from the inherent narrow momentum distribution of the atom source as well as its correlation properties. While these attributes represent clear advantages over laser-cooled sources, BEC production technology is considerably more demanding. With recent advances in rapid BEC production, the availability of commercial BEC systems, and even BECs in space, these technical challenges are being efficiently countered.

This Special Issue of Atoms will highlight recent work on BEC-based atom interferometry for fundamental physics and applications. Covering both experimental and theoretical aspects, it will provide a snapshot of the current status of this field. Topics of interest include precision measurements and quantum sensing, advances in interferometric techniques, and interferometry with correlated atomic states.

As BEC production and manipulation technology advances, we anticipate that this Special Issue will also serve as a useful resource for future work in the field of atom interferometry with Bose–Einstein condensates. We welcome original research articles as well as pedagogical reviews on specific topics.

A Sagnac atom interferometer can be constructed using a Bose–Einstein condensate trapped in a cylindrically symmetric harmonic potential. Using the Bragg interaction with a set of laser beams, the atoms can be launched into circular orbits, with two counterpropagating interferometers allowing many sources of common-mode noise to be excluded. In a perfectly symmetric and harmonic potential, the interferometer output would depend only on the rotation rate of the apparatus. However, deviations from the ideal case can lead to spurious phase shifts. These phase shifts have been theoretically analyzed for anharmonic perturbations up to quartic in the confining potential, as well as angular deviations of the laser beams, timing deviations of the laser pulses, and motional excitations of the initial condensate. Analytical and numerical results show the leading effects of the perturbations to be second order. The scaling of the phase shifts with the number of orbits and the trap axial frequency ratio are determined. The results indicate that sensitive parameters should be controlled at the 105 level to accommodate a rotation sensing accuracy of 109 rad/s. The leading-order perturbations are suppressed in the case of perfect cylindrical symmetry, even in the presence of anharmonicity and other errors. An experimental measurement of one of the perturbation terms is presented. Full article
