Phase response of atom interferometers based on sequential Bragg diffractions
B. Décamps, M. Bordoux, J. Alibert +2
Large Momentum Transfer (LMT) beam splitters are implemented in atom interferometers to increase their sensitivity. However, LMT-interferometer requires additional light-pulses tha…

Bell Correlations in a Bose-Einstein Condensate
Roman Schmied, Jean-Daniel Bancal, Baptiste Allard +4
Characterizing many-body systems through the quantum correlations between their constituent particles is a major goal of quantum physics. Although entanglement is routinely observe…

Sideband Rabi spectroscopy of finite-temperature trapped Bose gases
Baptiste Allard, Matteo Fadel, Roman Schmied +1
We use Rabi spectroscopy to explore the low-energy excitation spectrum of a finite-temperature Bose gas of rubidium atoms across the phase transition to a Bose-Einstein condensate…
