Confining the propagating wavepackets of an atom interferometer inside a waveguide can substantially reduce the size of the device while preserving high sensitivity. We have realized a twodimensional Sagnac atom interferometer in which Bose-condensed Rb atoms propagate within a tight waveguide formed by a collimated laser beam, a matter wave analog of the fiber optic gyro (FOG). The condensate is split, reflected, and recombined with a series of Bragg pulses while the waveguide moves… 

One second interrogation time in a 200 round-trip waveguide atom interferometer

We report a multiple-loop guided atom interferometer in which the atoms make 200 small-amplitude round-trips, instead of one large single orbit. The approach is enabled by using ultracold 39 K gas in

Interference dynamics of matter-waves of SU($N$) fermions

We analyze the two main physical observables related to the momenta of strongly correlated SU( N ) fermions in ring-shaped lattices pierced by an effective magnetic flux: homodyne (momentum

Implementation of an atomtronic SQUID in a strongly confined toroidal condensate

We investigate the dynamics of an atomtronic SQUID created by two mobile barriers, moving at two different, constant velocities in a quasi-1D toroidal condensate. We implement a multi-band truncated



Bose-Einstein-condensate interferometer with macroscopic arm separation

The basis of our study was to implement an atom interferometer using Rb Bose Einstein condensates which has advantages in sensitivity over current interferometers that use cold atoms and light.

Confinement effects in a guided-wave atom interferometer with millimeter-scale arm separation

Guided-wave atom interferometers measure interference effects using atoms held in a confining potential. In one common implementation, the confinement is primarily two dimensional, and the atoms move

Improved optical standing-wave beam splitters for dilute Bose–Einstein condensates

Bose–Einstein condensate (BEC)-based atom interferometry exploits low temperatures and long coherence lengths to facilitate high-precision measurements. Progress in atom interferometry promises

Quantum Rotation Sensing with Dual Sagnac Interferometers in an Atom-Optical Waveguide.

A Sagnac interferometer suitable for rotation sensing is described, implemented using an atomic Bose-Einstein condensate confined in a harmonic magnetic trap, and achieves a rotation sensitivity comparable to Earth's rate in about 10 min of operation.

Scalable Bose-Einstein-condensate Sagnac interferometer in a linear trap

We demonstrate a two-dimensional atom interferometer in a harmonic magnetic waveguide using a Bose-Einstein condensate. Such an interferometer could measure rotation using the Sagnac effect. Compared

Atom Michelson interferometer on a chip using a Bose-Einstein condensate.

An atom Michelson interferometer is implemented on an "atom chip." The chip uses lithographically patterned conductors and external magnetic fields to produce and guide a Bose-Einstein condensate.

A "folded figure 8" interfering configuration for creating a compact, large-area atom gyroscope with multiple-turn interfering paths is demonstrated.

Optical Ramsey spectroscopy in a rotating frame: Sagnac effect in a matter-wave interferometer.

A calcium atomic beam excited in an optical Ramsey geometry was rotated about an axis perpendicular to the plane defined by the laser beams and the atomic beam. A frequency shift of the Ramsey
