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 ...

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 ...

Philosophical Transactions of the Royal Society of London. Series A, Containing Papers of a Mathematical or Physical Character The Royal Society is a self-governing Fellowship of many of the world's ...

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 ...

Phonons bring good vibrations to quantum physicists. This is an Inside Science story. “I'm picking up good vibrations. She's giving me excitations.” Little did The Beach Boys know their 1966 hit was ...

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 ...

Sound is a type of energy made by vibrations. When an object, such as a guitar’s string, vibrates it causes the air particles around it to vibrate too. This is because the vibration of an object ...
