Microwave-dressed state-selective potentials for atom interferometry

New Journal of Physics, 2015
We propose a novel and robust technique to realize a beam splitter for trapped Bose–Einstein condensates (BECs). The scheme relies on the possibility of producing different potentials simultaneously for two internal atomic states.

Universal atom interferometer simulation of elastic scattering processes

Scientific Reports, 2020
In this article, we introduce a universal simulation framework covering all regimes of matter-wave light-pulse elastic scattering. Applied to atom interferometry as a study case, this simulator solves the atom-light diffraction problem in the elastic ...

Counterion Dependent Side‐Chain Relaxation Stiffens a Chemically Doped Thienothiophene Copolymer

Advanced Functional Materials, EarlyView.
Oxidation of a thienothiophene copolymer, p(g3TT‐T2), via different doping strategies and dopant molecules resulted in materials with similar oxidation levels and a high electrical conductivity of ≈100 S cm−1. However, mechanical properties varied significantly, with sub‐glass transition temperatures and elastic moduli spanning from –44°C to –3°C and ...

Atomic source selection in space-borne gravitational wave detection

New Journal of Physics, 2019
Recent proposals for space-borne gravitational wave detectors based on atom interferometry rely on extremely narrow single-photon transition lines as featured by alkaline-earth metals or atomic species with similar electronic configuration. Despite their
