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 ...

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 ...

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 ...

Physicists in China have uncovered new evidence that chiral phonons and magnons can interact strongly inside magnetic ...

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 ...

Almost anytime physicists announce that they’ve discovered a new particle, whether it’s the Higgs boson or the recently bagged double-charm tetraquark, what they’ve actually spotted is a small bump ...

Substances can exist in three states of matter - solid, liquid and gas. All substances are made from particles, and the forces between the particles are different in solids, liquids and gases. The ...
