Fluorescent bulbs can be lit up without a light fixture, but it takes caution.

Measurements of the optical response of 2-D transition-metal dichalcogenides have now pinpointed real material systems in which a hypothesized light-squeezing quasiparticle can form. The 2-D ...

The famous double-slit experiment, which demonstrated that light is both a wave and a particle, has been performed using “slits in time”. The techniques involved present a new way to manipulate light ...

A new experiment has demonstrated something that sounds physically impossible – light itself casting a shadow. It turns out that if you manipulate a laser just right, then hit it side-on with another ...

Imperial physicists have recreated the famous double-slit experiment, which showed light behaving as particles and a wave, in time rather than space. The experiment relies on materials that can change ...

Scientists observe a visible time crystal for the first time, revealing a phase of matter that repeats patterns through time.
