Doppler-tuned Bragg Spectroscopy of Excited Levels in He-Like Uranium: a discussion of the uncertainty contributions
Martino Trassinelli, Ajay Kumar, H. F. Beyer +4
We present the uncertainty discussion of a recent experiment performed at the GSI storage ring ESR for the accurate energy measurement of the He-like uranium 1s2p3P2- 1s2s3S1 intra…
Spatiotemporal heterodyne detection
Michael Atlan, Michel Gross
We describe a scheme into which a camera is turned into an efficient tunable frequency filter of a few Hertz bandwidth in an off-axis, heterodyne optical mixing configuration, enab…
Repulsive Casimir forces and the role of surface modes
I. Pirozhenko, A. Lambrecht
The Casimir repulsion between a metal and a dielectric suspended in a liquid has been thoroughly studied in recent experiments. In the present paper we consider surface modes in th…
Ground state of a tightly bound composite dimer immersed in a Fermi Sea
Christophe Mora, Frédéric Chevy
In this paper we present a theoretical investigation for the ground state of an impurity immersed in a Fermi sea. The molecular regime is considered where a two-body bound state be…
Effect of vortices on the spin-flip lifetime of atoms in superconducting atom-chips
Gilles Nogues, Cédric Roux, Thomas Nirrengarten +7
We study theoretically the lifetime of magnetically trapped atoms in the close vicinity of a type-II superconducting surface, in the context of superconducting atom-chips. We accou…
Ultracold Fermions in a Graphene-Type Optical Lattice
Kean Loon Lee, Benoit Gremaud, Rui Han +2
Some important features of the graphene physics can be reproduced by loading ultracold fermionic atoms in a two-dimensional optical lattice with honeycomb symmetry and we address h…
