Sympathetic cooling with ultracold atoms and atomic ions enables ultralow temperatures in systems where direct laser or evaporative cooling is not possible. It has so far been limited to the cooling of other microscopic particles, with masses up to $

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 an

We present experiments on optical writing and erasing of microscopic magnetic domain patterns on an epitaxial ferrite-garnet film. The film is initially uniformly magnetized normally to the surface. A weak constant magnetic field pointing in the same

We report on the realization of a hybrid optomechanical system in which ultracold atoms are coupled to a micromechanical membrane. The atoms are trapped in the intensity maxima of an optical standing wave formed by retroreflection of a laser beam fro

Physical Review A
We discuss a hybrid quantum system where a dielectric membrane situated inside an optical cavity is coupled to a distant atomic ensemble trapped in an optical lattice. The coupling is mediated by the exchange of sideband photons of the lattice laser,

An optical lattice formed by reflection from a SiN x membrane creates a bidirectional coupling of atomic and membrane motion. We measure the influence of the atoms on the membrane and explore causes of mechanical dissipation.

An optical lattice formed by reflection from a SiN$_x$ membrane creates a bi-directional coupling of atomic and membrane motion. Experimental demonstrations of both direct-action and backaction in this system are reported.

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 u

The authors demonstrate all-optical reversible switching of the magnetization direction in a uniformly magnetized ferrite-garnet film. The magnetization is switched by locally heating the film with a pulsed laser beam. The direction to which the magn
