Quantum interference test of the equivalence principle on antihydrogen
P. -P. Crépin, C. Christen, R. Guérout +3
We propose to use quantum interferences to improve the accuracy of the measurement of the free fall acceleration g of antihydrogen in the GBAR experiment. This method uses most ant…
Quantum reflection of antihydrogen from a liquid helium film
P. -P. Crépin, E. A. Kupriyanova, R. Guérout +5
We study the quantum reflection of ultracold antihydrogen atoms bouncing on the surface of a liquid helium film. The Casimir-Polder potential and quantum reflection are calculated…
Casimir-Polder force fluctuations as spatial probes of dissipation in metals
Nicolas Cherroret, Pierre-Philippe Crépin, Romaint Guérout +2
We study the spatial fluctuations of the Casimir-Polder force experienced by an atom or a small sphere moved above a metallic plate at fixed separation distance. We demonstrate tha…
Casimir-Polder shifts on quantum levitation states
P. -P. Crépin, G. Dufour, R. Guérout +2
An ultracold atom above a horizontal mirror experiences quantum reflection from the attractive Casimir-Polder interaction, which holds it against gravity and leads to quantum levit…
Hydrodynamic spectrum of a superfluid in an elongated trap
Pierre-Philippe Crépin, Xavier Leyronas, Frédéric Chevy
--In this article we study the hydrodynamic spectrum of a superfluid confined in a cylindrical trap. We show that the dispersion relation (q) of the phonon branch scales like $\…
