Levitating sensors are moving from science-fiction imagery to practical laboratory tools, promising a new generation of instruments that can feel forces so faint they border on the gravitational pull ...

ETH Zurich scientists have levitated a tower of three nano glass spheres using optical tweezers, suppressing almost all classical motion to observe quantum zero-point fluctuations with unprecedented ...

With the help of an optical device and laser beams, researchers at ETH Zurich have succeeded in keeping such objects almost completely motionless in levitation. This is significant when it comes to ...

With a clever design, researchers have solved eddy-current damping in macroscopic levitating systems, paving the way for a wide range of sensing technologies Levitation has long been pursued by stage ...

ETH Zurich researchers captured a nano-object (centre of the image) using a laser trap. The laser light, which is focused with a lens, is shown in red. Three nano glass spheres cling to one another.
