Chiral phonons are groups of atoms that move in a circular direction when excited by an energy source, such as heat. As the phonons move through a material, they propagate that circular motion, or angular momentum, through ...
Scientists at Los Alamos National Laboratory have demonstrated a new quantum-dot mechanism that could significantly expand the reach of light-driven chemistry. By introducing magnetic manganese dopants into semiconductor ...
Researchers in the Department of Electrical and Computer Engineering at the University of Illinois Urbana-Champaign have discovered a new type of quantum light emitter in diamonds that could help overcome a number of challenges ...
Plants need nitrogen fertilizers, which are usually ammonia-based. Ammonia is therefore one of the most important chemical products. However, its production is currently extremely energy-intensive. An international team from ...
A new concept from Warwick researchers could help solve one of the biggest challenges to building large-scale quantum computers: enabling communication between vast numbers of quantum bits (qubits) over long distances across ...
Efficient heat management in solids is key to advancing the next generation of electronics. However, wave-like heat movement—known as phonon focusing—had been observed only at extremely low, or cryogenic, temperatures, limiting ...
Physicists have long puzzled over a strange contradiction inside a family of minerals called rutile oxides. These materials all share the same crystal structure—but while some of them, like titanium dioxide, are firmly insulating, ...
An international research team has demonstrated that the intrinsic disorder of the compound semiconductor CuInSnS₄ can be exploited to influence its optical properties. While the atomic vibrations also sense the local disorder, ...
Physicists at Paderborn University have, for the first time, experimentally demonstrated the so-called "return" of Rabi oscillations in semiconductor quantum dots. The phenomenon, which was first predicted theoretically in ...
In an international experiment, researchers observed Jahn–Teller polarons—quasiparticles that could play an important role in future ultrafast spintronic devices. These polarons emerged within the crystal lattice of cobalt ...
