Testing gravity with cold atom interferometry: results and prospects [PDF]

open access: yesQuantum Science and Technology, 2020
Atom interferometers have been developed in the last three decades as new powerful tools to investigate gravity. They were used for measuring the gravity acceleration, the gravity gradient, and the gravity-field curvature, for the determination of the ...

Space-borne Bose–Einstein condensation for precision interferometry [PDF]

open access: yesNature, 2018
Owing to the low-gravity conditions in space, space-borne laboratories enable experiments with extended free-fall times. Because Bose–Einstein condensates have an extremely low expansion energy, space-borne atom interferometers based on Bose–Einstein ...

Landau-Zener-Stuckelberg interferometry [PDF]

open access: yes, 2010
A transition between energy levels at an avoided crossing is known as a Landau-Zener transition. When a two-level system (TLS) is subject to periodic driving with sufficiently large amplitude, a sequence of transitions occurs.

Broadband spectral shaping using nematic liquid crystal

open access: yesResults in Physics, 2019
We demonstrate what is, to our knowledge, the first implementation of nematic liquid crystal (LC) for spectral shaping of broadband light fields. A LC cell of several microns thickness is placed between a polarizer and an analyzer.

Stellar Intensity Interferometry: Astrophysical targets for sub-milliarcsecond imaging [PDF]

open access: yes, 2010
Intensity interferometry permits very long optical baselines and the observation of sub-milliarcsecond structures. Using planned kilometric arrays of air Cherenkov telescopes at short wavelengths, intensity interferometry may increase the spatial ...

Sensitivity of a Bolometric Interferometer to the CMB power spectrum [PDF]

open access: yes, 2008
Context. The search for B-mode polarization fluctuations in the Cosmic Microwave Background is one of the main challenges of modern cosmology. The expected level of the B-mode signal is very low and therefore requires the development of highly sensitive ...
