There is urgent need to develop new acceleration techniques capable of exceeding gigaelectron-volt-per-metre (GeV m −1) gradients in order to enable future generations of both light sources and ...

In some cases, the thinning of the interface also generates a gradient in surface tension. Essentially, the water drains out, leaving a higher soap concentration.

A quantum gravity gradient sensor developed by researchers in the UK has been used outdoors to locate a small underground structure. Using a pair of vertically oriented atom interferometers that are ...
