Studying mechanical resonators via radiation pressure offers a rich avenue for the
exploration of quantum mechanical behavior in a macroscopic regime. However, quantum …

Utilizing the tools of quantum optics to prepare and manipulate quantum states of motion of
a mechanical resonator is currently one of the most promising routes to explore non …

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 transition from quantum to classical physics remains an intensely debated question
even though it has been investigated for more than a century. Further clarifications could be …

We discuss hybrid systems in which a mechanical oscillator is coupled to another
(microscopic) quantum system, such as trapped atoms or ions, solid-state spin qubits, or …

We establish a method of directly measuring and estimating nonclassicality—operationally
defined in terms of the distinguishability of a given state from one with a positive Wigner …

We study a device formed by a Bose-Einstein condensate (BEC) coupled to the field of a
cavity with a moving end mirror and find a working point such that the mirror-light …

We discuss interfacing trapped atomic systems with solid-state systems such as
superconducting Josephson-junction devices or nanomechanical oscillators. Such hybrid …

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 …

The macroscopic tunneling of an optomechanical membrane is considered. A cavity mode
which couples quadratically to the membranes position can create highly tunable adiabatic …
