How does light turn into motion within a metal? A team of researchers from European XFEL, the University of Potsdam and other participating institutions has shown that ultrashort optical laser pulses can trigger extremely ...
An international team of researchers has reported a major advance in understanding quantum dynamics in semiconductor materials. They directly observed how excitons and phonons evolve together in perovskite nanocrystals, revealing ...
Waves of light and sound interact to drive electronic and structural changes in a perovskite crystal. At the atomic scale, nothing is ever truly still. Materials that appear perfectly rigid and motionless to the naked eye ...
For every action, there is an equal and opposite reaction. What goes up must come down. Physical laws like these govern all of the natural world—except for the tiny internal components of today's microprocessors, which operate ...
Heat behaves in predictable ways: a hot cup of coffee cools, a laptop warms your hands, the sun heats Earth. But at scales thousands of times smaller than a human hair, those rules begin to break down, and scientists are ...
When a singer belts out a tune while a guitar player strums along, sound waves travel through the air, driving collective oscillations of the molecules within. Meanwhile, at the quantum level, something similar is going on. ...
Controlling heat flow is a major challenge for many technologies. In electronic and photonic devices, for example, heat dissipation can limit the performance and efficiency, as well as their potential for further miniaturization. ...
Researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have demonstrated, for the first time, a single quantum of vibrational energy interacting with a single atomic spin, seeding a pathway ...
Your phone warms up after a 20-minute FaceTime call. Your laptop hums loudly while editing a large video file. Heat is a by-product of modern electronics—from everyday gadgets to the high-resolution screens and processors ...
Superconductors are materials that can conduct electricity with a resistance of zero. In so-called conventional superconductors, this occurs at low temperatures when electrons become bound into pairs, known as Cooper pairs.
