Physicists in China have uncovered new evidence that chiral phonons and magnons can interact strongly inside magnetic crystals. Using neutron spectroscopy, a team led by Song Bao at Nanjing University ...

In solid materials with regular atomic structures, figuring out weak points where the material will break under stress is relatively easy. But for disordered solids, like glass or sand, their ...

Scientists investigated the excitation and detection of photogenerated coherent phonons in polar semiconductor GaAs through an ultrafast dual pump-probe laser for quantum interferometry. Scientists at ...

Imagine a world where computers can store, move, and process information at exponential speeds using what we currently term as waste vibrations—heat and noise. While this may remind us of a sci-fi ...

Chances are you’ve seen the gorgeous patterns that sound waves produce when sand is sprinkled on a vibrating metal plate. Now French physicists have produced inverse versions of these patterns using ...

Sometimes the knowledge is already there – it has just been overlooked. For about half a century, physicists have puzzled over vibrations in glass at low temperatures. The reason: Glass carries sound ...

It’s not unusual for me to receive mail questioning quantum mechanics and special relativity. I’ll admit, these ideas can sound a bit crazy. For some people, these ideas are simply too ...
