Scientists find holes in light by tying it in knots

A research collaboration including theoretical physicists from the University of Bristol and Birmingham has found a new way of evaluating how light flows through space—by tying knots in it.

Ultracold atoms and ultrafast lasers

Two separate research fields have been united in Hamburg for the very first time. Ultrashort laser pulses enable us to observe and manipulate matter on very short time scales, whereas ultracold atoms permit experiments with ...

Enter BIFROST—physicists get their own rainbow bridge

In Norse mythology, the Bifrost was the rainbow bridge linking the realm of the gods to Earth. At UC Santa Barbara, it is also the name of the Broadly-tunable Illumination Facility for Research, Outreach, Scholarship, and ...

New IR instrument searches for habitable planets

A new instrument to search for potentially habitable/inhabited planets has started operation at the Subaru Telescope. This instrument, IRD (InfraRed Doppler), will look for habitable planets around red dwarf stars. Astronomers ...

Multiple lasers could be replaced by a single microcomb

Every time we send an e-mail, a tweet, or stream a video, we rely on laser light to transfer digital information over a complex network of optical fibers. Dozens of high-performance lasers are needed to fill up the bandwidth ...
