Test of the He-McKellar-Wilkens topological phase by atom interferometry. Part I: theoretical discussion
Steven Lepoutre, Alexandre Gauguet, Matthias Büchner +1
We have recently tested the topological phase predicted by He and McKellar and by Wilkens: this phase appears when an electric dipole propagates in a transverse magnetic field. In…
Test of the He-McKellar-Wilkens topological phase by atom interferometry. Part II: the experiment and its results
Steven Lepoutre, Jonathan Gillot, Alexandre Gauguet +2
In this paper, we describe an experimental test of the He-McKellar-Wilkens (HMW) topological phase with our lithium atom interferometer. The expected value of the HMW phase shift i…
Storage and control of optical photons using Rydberg polaritons
D. Maxwell, D. J. Szwer, D. P. Barato +6
We use a microwave field to control the quantum state of optical photons stored in a cold atomic cloud. The photons are stored in highly excited collective states (Rydberg polarito…
