Mechanical systems are ideal candidates for studying quantum behavior of macroscopic
objects. To this end, a mechanical resonator has to be cooled to its ground state and its …

In the last decade we have witnessed exciting technological advances in the fabrication and
control of microelectromechanical and nanoelectromechanical systems (MEMS & NEMS)[1 …

Bistable mechanical vibration is observed in a cavity magnomechanical system, which
consists of a microwave cavity mode, a magnon mode, and a mechanical vibration mode of …

The theory of damping is discussed in Newton's Principia and has been tested in objects as
diverse as the Foucault pendulum, the mirrors in gravitational-wave detectors and …

Wigner functions and Weyl transforms of operators offer a formulation of quantum mechanics
that is equivalent to the standard approach given by the Schrödinger equation. We give a …

We study an open quantum system of atoms with a long-range Rydberg interaction, laser
driving, and spontaneous emission. Over time, the system occasionally jumps between a …

We have measured the optical and mechanical loss of commercial silicon nitride
membranes. We find that 50 nm thick, 1 mm 2 membranes have mechanical Q> 10 6 at 293 …

This is a text on quantum mechanics formulated simultaneously in terms of position and
momentum, ie in phase space. It is written at an introductory level, drawing on the …

We establish the emergence of chaotic motion in optomechanical systems. Chaos appears
at negative detuning for experimentally accessible values of the pump power and other …

Nano-mechanical resonators have gained an increasing importance in nanotechnology
owing to their contributions to both fundamental and applied science. Yet, their small …
