The quest for realizing and manipulating ever smaller man-made movable structures and
dynamical machines has spurred tremendous endeavors, led to important discoveries, and …

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

By exploiting recent developments associated with coupled microcavities, we introduce the
concept of the PT-symmetric phonon laser with balanced gain and loss. This is …

Guiding waves through a stable physical channel is essential for reliable information
transport. However, energy transport in high-frequency mechanical systems, such as in …

Mechanical resonators are important components of devices that range from gravitational
wave detectors to cellular telephones. They serve as high-performance transducers, sensors …

Micro-and nanoelectromechanical systems have numerous applications in sensing and
signal transduction. Many properties benefit from reducing the system size to the nanoscale …

The dynamics of nonlinear systems qualitatively change depending on their parameters,
which is called bifurcation. A quantum-mechanical nonlinear oscillator can yield a quantum …

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 study the dynamics of a driven optomechanical cavity coupled to a charged
nanomechanical resonator via Coulomb interaction, in which the tunable double …

Understanding and controlling vibrations in condensed matter is emerging as an essential
necessity both at fundamental level and for the development of a broad variety of …
