Mechanical Engineering Professor Alan McGaughey of Carnegie Mellon University recently coordinated the Phonon Olympics, bringing together developers and expert users to benchmark three leading open-source thermal conductivity ...
A theoretical framework predicts the emergence of non-reciprocal interactions that effectively violate Newton's third law in solids using light, report researchers from Japan. They demonstrate that by irradiating light of ...
Using ultra-fast laser beams, a team from the Irradiated Solids Laboratory has designed an experiment that allows both the creation of nanometric cavities in metal films and their study using several advanced microscopy techniques. ...
University of Houston researchers have made a discovery in thermal conductivity that overturns an existing theory that boron arsenide (BAs) couldn't compete with the heat conduction of a diamond.
Ferroic materials such as ferromagnets and ferroelectrics underpin modern data storage, yet face limits: They switch slowly, or suffer from unstable polarization due to depolarizing fields respectively. A new class, ferroaxials, ...
An international team of researchers has developed a novel technique to efficiently excite and control highly-confined light-matter waves, known as higher-order hyperbolic phonon polaritons. Their method not only sets new ...
Researchers have created a chip-based device that can split phonons—tiny packets of mechanical vibration that can carry information in quantum systems. By filling a key gap, this device could help connect various quantum ...
Atoms in crystalline solids sometimes vibrate in unison, giving rise to emergent phenomena known as phonons. Because these collective vibrations set the pace for how heat and energy move through materials, they play a central ...
In a world-first, researchers from the Femtosecond Spectroscopy Unit at the Okinawa Institute of Science and Technology (OIST) have directly observed the evolution of the elusive dark excitons in atomically thin materials, ...
Researchers at the University of California, Irvine, together with international collaborators, have developed a new electron microscopy method that has enabled the first-ever imaging of vibrations, or phonons, in specific ...
