Phonons are the quantum units of mechanical vibration. They describe how motion propagates through a solid at the smallest possible scales, in much the same way that electrons describe electric ...

The universe, according to quantum mechanics, is built out of probabilities. An electron is neither here nor there but instead has a likelihood of being in multiple locations—more a cloud of ...

A team of Johns Hopkins engineers has developed a new, more powerful method to observe molecular vibrations, an advance that could have far-reaching implications for early disease detection. The team, ...
