Physicists coax superconductivity and more from quasicrystals

 Physics General News
 29 September 2023
In research that could jumpstart interest into an enigmatic class of materials known as quasicrystals, MIT scientists and colleagues have discovered a relatively simple, flexible way to create new atomically thin versions that can be tuned for important phenomena. In work reported in Nature they...

Intense lasers shine new light on the electron dynamics of liquids

 Physics General News
 28 September 2023
An international team of researchers from the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) in Hamburg and ETH Zurich has now demonstrated that it is possible to probe electron dynamics in liquids using intense laser fields and to retrieve the electron mean free path—the...

Revolutionary X-ray microscope unveils sound waves deep within crystals

 Physics General News
 28 September 2023
Researchers at the Department of Energy's SLAC National Accelerator Laboratory. Stanford University, and Denmark Technical University have designed a cutting-edge X-ray microscope capable of directly observing sound waves at the tiniest of scales—the lattice level within a crystal. These findings,...

Recent manipulations of excitons in moiré superlattices

 Physics General News
 28 September 2023
Light can excite electron and hole pairs inside semiconducting materials. If the attraction between a negatively charged electron and a positively charged hole (the antiparticle of electron in solid state physics) is strong, they stay bound together, forming states known as excitons. In these...

Curving light in a record-setting way

 Physics General News
 27 September 2023
A team led by scientists and engineers from the University of Wisconsin-Madison, the University of Southern California and Washington University in St. Louis, has created a unique, record-setting material that can bend one infrared ray of light in two directions....
