Twin-lattice atom interferometry [PDF]

Nature Communications, 2021
Atom interferometers can be useful for precision measurement of fundamental constants and sensors of different type. Here the authors demonstrate a compact twin-lattice atom interferometry exploiting Bose-Einstein condensates (BECs) of 87 Rb atoms.

Ultracold atom interferometry in space [PDF]

Nature Communications, 2021
Conducting atom-optical experiments in space is interesting for fundamental physics and challenging due to different environment compared to ground. Here the authors report matter-wave interferometry in space using atomic BECs in a sounding rocket.

Mach-Zehnder atom interferometry with non-interacting trapped Bose-Einstein condensates [PDF]

Nature Communications
The coherent manipulation of a quantum wave is at the core of quantum sensing. For instance, atom interferometers require splitting and recombination processes to map the accumulated phase shift into a measurable population signal. Although Bose-Einstein

Microwave Atom Chip Design

Atoms, 2021
We present a toolbox of microstrip building blocks for microwave atom chips geared towards trapped atom interferometry. Transverse trapping potentials based on the AC Zeeman (ACZ) effect can be formed from the combined microwave magnetic near fields of a

Robust atom optics for Bragg atom interferometry

New Journal of Physics, 2023
Multi-photon Bragg diffraction is a powerful method for fast, coherent momentum transfer of atom waves. However, laser noise, Doppler detunings, and cloud expansion limit its efficiency in large momentum transfer (LMT) pulse sequences.
