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鈥攖iny 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 ...
While many plans for quantum computers transmit data using the particles of light known as photons, researchers from the University of Chicago Pritzker School of Molecular Engineering (UChicago PME) are turning to sound.
Copper selenide (Cu鈧係e) attracts scientific interest for its thermoelectric ability to convert heat into electricity, but a lack of atomic-level understanding has limited its practical applications for decades.
Caltech scientists have developed an artificial intelligence (AI)鈥揵ased method that dramatically speeds up calculations of the quantum interactions that take place in materials. In new work, the group focuses on interactions ...
