A rainbow reveals with colors what otherwise remains hidden: light is "refracted" by transparent matter, in this case water droplets. This same physical effect underlies many everyday technologies, ...

A new theory, that explains how light and matter interact at the quantum level has enabled researchers to define for the first time the precise shape of a single photon. A new theory, that explains ...

Over the past decades, many research teams worldwide have been trying to detect dark matter, an elusive type of matter that does not emit, reflect or absorb light, using a variety of highly sensitive ...

Within our comfortable world of causality we expect that reactions always follow an action and not vice versa. This why the recent chatter in the media about researchers having discovered ‘negative ...

Photon–atom interactions in nanophotonic systems exploit the tight confinement of light in subwavelength structures to enhance and precisely engineer light–matter coupling at the single-quantum level.
