New regime in the Casimir force observed

By nanostructuring one of two interacting metal surfaces at scales below the plasma wavelength, a new regime in the Casimir force was observed by Argonne National Laboratory researchers in the Center for Nanoscale Materials ...

Revisiting quantum effects in MEMS

New calculations shows that the influence of quantum effects on the operating conditions of nanodevices has, until now, been overestimated.

Calculating quantum vacuum forces in nanostructures

(Phys.org)—One of the surprising predictions of quantum mechanics is that uncharged conductors can attract each other over small distances, even in empty space. While the resulting "Casimir force" has been accurately measured ...

Raising the prospects for quantum levitation

More than half-a-century ago, the Dutch theoretical physicist Hendrik Casimir calculated that two mirrors placed facing each other in a vacuum would attract. The mysterious force arises from the energy of virtual particles ...

New way to calculate the effects of Casimir forces

(PhysOrg.com) -- MIT researchers have developed a powerful new tool for calculating the effects of Casimir forces, complicated quantum forces that affect only objects that are very, very close together, with ramifications ...

Metamaterials could reduce friction in nanomachines

(PhysOrg.com) -- Nanoscale machines expected to have wide application in industry, energy, medicine and other fields may someday operate far more efficiently thanks to important theoretical discoveries concerning the manipulation ...

Researchers see exotic force for first time

(PhysOrg.com) -- For the first time, researchers have measured a long-theorized force that operates at distances so tiny they’re measured in billionths of a meter, which may have important applications in nanotechnology ...
