Coupling ultracold atoms to mechanical oscillators
Wed, 2011-09-28 14:46 - Donatella RosettiC. R. Physique, accepted for publication preprint arXiv:1103.1820 (2011)
In this article we discuss and compare different ways to engineer an interface between ultracold atoms and micro- and nanomechanical oscillators. We start by analyzing a direct mechanical coupling of a single atom or ion to a mechanical oscillator and show that the very different masses of the two systems place a limit on the achievable coupling constant in this scheme.

We have realized a hybrid optomechanical system by coupling ultracold atoms to a micromechanical membrane. The atoms are trapped in an optical lattice, which is formed by retro-reflection of a laser beam from the membrane surface. In this setup, the lattice laser light mediates an optomechanical coupling between membrane vibrations and atomic center-of-mass motion. We observe both the effect of the membrane vibrations onto the atoms as well as the backaction of the atomic motion onto the membrane.

We measure the frequency dependence of the mechanical quality factor (Q) of SiN membrane oscillators and observe a resonant variation of Q by more than two orders of magnitude. The frequency of the fundamental mechanical mode is tuned reversibly by up to 40% through local heating with a laser. Several distinct resonances in Q are observed that can be explained by coupling to membrane frame modes. Away from the resonances, the background Q is independent of frequency and temperature in the measured range.
UNIBAS as a new partner in the AQUTE Consortium
Mon, 2011-09-26 15:00 - Donatella RosettiUniversität Basel (UNIBAS) is a new partner in the AQUTE Consortium
On the 4th of February 2011 the European Commission has sent us the official approval to our request to add Basel Universität (UNIBAS) among the AQUTE partners, following the move of Professor Philipp Treutlein from München (LMU, AQUTE partner P11) to Basel.
