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

Radio-frequency communication systems have long used bulk-and surface-acoustic-wave
devices supporting ultrasonic mechanical waves to manipulate and sense signals. These …

Numerous astrophysical and cosmological observations are best explained by the existence
of dark matter, a mass density which interacts only very weakly with visible, baryonic matter …

The small mass and high coherence of nanomechanical resonators render them the ultimate
mechanical probe, with applications that range from protein mass spectrometry and …

Optically trapped nanospheres in high vacuum experience little friction and hence are
promising for ultrasensitive force detection. Here we demonstrate measurement times …

For decades, mechanical resonators with high sensitivity have been realized using thin‐film
materials under high tensile loads. Although there are remarkable strides in achieving low …

Energy dissipation is an unavoidable phenomenon of physical systems that are directly
coupled to an external environmental bath. In an oscillatory system, it leads to the decay of …

We discuss effects of loss of coherence in low energy quantum systems caused by or related
to gravitation, referred to as gravitational decoherence. These effects, resulting from random …

In force sensing, optomechanics, and quantum motion experiments, it is typically
advantageous to create lightweight, compliant mechanical elements with the lowest possible …

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