We report the experimental realization of a bosonic Kitaev chain in a nano-optomechanical network.

Ce Zhang and colleagues report a novel system based on a software-defined radio to measure and control the vibrations of an exotic nanomechanical graphene resonator. This system will be helpful for the nanomechanical measurements with small signals and modulations.

Yi-Te Huang and colleagues demonstrate a microactuator driven by a spin-current volume effect. Alternating current and external magnetic field generates mechanical resonances in the amorphous magnetic film TbFeCo layered with non-magnetic metal.

This Review discusses advances in engineering high-quality-factor strained nanomechanical resonators with applications in precision measurements.

The planar structure of thin-film piezoelectric resonators limits the integration of multiband processors on a single chip. A three-dimensional nanomechanical resonator based on conformal ferroelectric gates to excite resonance in scalable silicon fins is shown to enable multiband integration on a single chip and to facilitate densification of processors for ultrawide-band wireless communication.

A coherent interface between a mechanical oscillator and superconducting electrical circuits would enable the control of quantum states of mechanical motion, but such interfaces often result in excess mechanical energy loss. A new material-agnostic approach is shown to achieve strong electromechanical coupling while preserving a long phonon lifetime.

Quantum mechanical fluctuations of the electromagnetic field in a vacuum between two close together objects result in an attractive force. Now, it has been experimentally shown that by exploiting a similar repulsive interaction, attraction between objects can be modulated simply by tuning temperature.

The phase, frequency and amplitude of gigahertz acoustic waves can be electrically controlled in a lithium niobate waveguide at millikelvin temperatures.

Graphene and related two-dimensional (2D) materials have remained an active field of research in science and engineering for over fifteen years. Here, the authors investigate why the transition from laboratories to fabrication plants appears to lag behind expectations, and summarize the main challenges and opportunities that have thus far prevented the commercialisation of these materials.
