Ultrafast light pulses make molecules rotate on quantum materials

Researchers from Germany, Japan and India, led by scientists from DESY and the Universities of Kiel and Hamburg, have found a way to collectively make molecules on a flat surface rotate by exposing them to light using ultrafast ...

Engineers improve infrared devices using century-old materials

After decades of intense research, surprises in the realm of semiconductors—materials used in microchips to control electrical currents—are few and far between. But with a pair of published papers, materials engineers ...

Trapping light on thermal photodetectors shatters speed records

Electrical engineers at Duke University have demonstrated the fastest pyroelectric photodetector to date, which works by absorbing heat generated by incoming light. Capable of capturing light from the entire electromagnetic ...

Möbius-inspired surface controls light in two directions

Light is an unusually rich carrier of information. Its direction of travel, wavelength, and polarization can all be used to encode signals or images. Yet controlling these properties independently remains difficult, especially ...

Laser-within-a-laser delivers MeV X-ray radiography in picoseconds

Lawrence Livermore National Laboratory's National Ignition Facility (NIF) is the hottest place on Earth for the briefest of moments during an experiment. Now, it can be one of the brightest places thanks to the Advanced Radiographic ...

Clearing the path for turbulence-free quantum communication

A University of Ottawa team has developed a new way to protect free-space quantum key distribution (QKD) from atmospheric turbulence, one of the main causes of distortion and errors when sending quantum information through ...
