Nanomechanics has brought mesoscopic physics into the world of vibrations. Because
nanomechanical systems are small, fluctuations are significant, the vibrations already …

The control of individual quantum systems is now a reality in a variety of physical settings.
Feedback control is an important class of control methods because of its ability to reduce the …

According to quantum mechanics, a harmonic oscillator can never be completely at rest.
Even in the ground state, its position will always have fluctuations, called the zero-point …

Quality factor (Q) is an important property of micro-and nano-electromechanical (MEM/NEM)
resonators that underlie timing references, frequency sources, atomic force microscopes …

We discuss how large amounts of steady-state quantum squeezing (beyond 3 dB) of a
mechanical resonator can be obtained by driving an optomechanical cavity with two control …

Quantum squeezing in mechanical systems is not only a key signature of macroscopic
quantum effects, but can also be utilized to advance the metrology of weak forces. Here we …

The quantum nonlinear regime of optomechanics is reached when nonlinear effects of the
radiation pressure interaction are observed at the single-photon level. This requires …

We report an efficient mechanism to generate a squeezed state of a mechanical mirror in an
optomechanical system. We use an especially tuned parametric amplifier (PA) inside the …

While the squeezing of a propagating field can, in principle, be made arbitrarily strong, the
cavity-field squeezing is subject to the well-known 3 dB limit, and thus has limited …

We theoretically show that strong mechanical quantum squeezing in a linear
optomechanical system can be rapidly generated through the dynamical instability reached …
