Quantum fluctuations give rise to van der Waals and Casimir forces that dominate the interaction between electrically neutral objects at sub-micron separations. Under the trend of miniaturization, such quantum electrodynamical effects are expected to play an important role in micro- and nano-mechanical devices. Nevertheless, utilization of Casimir forces on the chip level remains a major challenge because all experiments so far require an external object to be manually positioned close to the… 

Strong geometry dependence of the Casimir force between interpenetrated rectangular gratings

This work shows that the presence of gratings can strongly modify the Casimir force to control the interaction between nanomechanical components.

The Casimir effect between micromechanical components on a silicon chip

The Casimir force originates from quantum fluctuations. While this force is too weak to have any measurable effects between objects at separations larger than ~10 μm it dominates the interaction

Measurement of non-monotonic Casimir forces between silicon nanostructures

Previous demonstrations of the elusive Casimir force between interfaces exhibit monotonic dependence on surface displacement. Now a non-monotonic dependence of the force has been shown experimentally

Rigorous analysis of Casimir and van der Waals forces on a silicon nano-optomechanical device actuated by optical forces.

This work presents a rigorous analysis of the dispersion forces on a nano-optomechanical device based on a silicon waveguide and a silicon dioxide substrate, surrounded by air and driven by optical forces.

Building a Casimir Metrology Platform with a Commercial MEMS Accelerometer.

The Casimir Effect is a physical manifestation of quantum fluctuations of the electromagnetic vacuum. When two metal plates are placed closely together, typically much less than a micron, the long

Nanocorrugation-Induced Forces between Electrically Neutral Metallic Objects.

It is shown that there is a kind of curvature-induced force that acts between nanocorrugated electrically neutral metallic surfaces, and its magnitude is comparable to light-induced forces acting on plasmonic nano-objects.

Casimir spring and dilution in macroscopic cavity optomechanics

The Casimir force was predicted in 1948 as a force arising between macroscopic bodies from the zero-point energy. At finite temperatures, it has been shown that a thermal Casimir force exists due to

Here, we discuss possible applications of the Casimir forces in micro- and nanosystems. The main part of this paper is devoted to actuation with quantum fluctuations and to the relative contribution

We investigate the effect of Casimir force on a silicon nano-opto-electro-mechanical system (NOEMS) device, based on a slot-waveguide structure and driven by optical forces. Light is strongly



The Casimir effect in microstructured geometries

In 1948, Hendrik Casimir predicted that a generalized version of van der Waals forces would arise between two metal plates due to quantum fluctuations of the electromagnetic field. These forces

Quantum Mechanical Actuation of Microelectromechanical Systems by the Casimir Force

This work demonstrates the Casimir effect in microelectromechanical systems using a micromachined torsional device and shows that quantum electrodynamical effects play a significant role when the separation between components is in the nanometer range.

Measured long-range repulsive Casimir–Lifshitz forces

It is shown experimentally that the sign of the force can be changed from attractive to repulsive by suitable choice of interacting materials immersed in a fluid, and the measured repulsive interaction is found to be weaker than the attractive.

Measurement of the Casimir force between a gold sphere and a silicon surface with nanoscale trench arrays.

Measurements of the Casimir force between a gold sphere and a silicon surface with an array of nanoscale, rectangular corrugations using a micromechanical torsional oscillator show strong dependence on the shape of the interacting bodies, possibly due to the interplay between finite conductivity and geometry effects.
