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 (Cuâ‚‚Se) 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)–based method that dramatically speeds up calculations of the quantum interactions that take place in materials. In new work, the group focuses on interactions ...
A new study has successfully demonstrated the confinement of terahertz (THz) light to nanoscale dimensions using a new type of layered material. This could lead to improvements in optoelectronic devices such as infrared emitters ...
Cornell Engineering researchers have demonstrated that, by zapping a synthetic thin film with ultrafast pulses of low-frequency infrared light, they can cause its lattice to atomically expand and contract billions of times ...
Over the past decades, many research teams worldwide have been trying to detect dark matter, an elusive type of matter that does not emit, reflect or absorb light, using a variety of highly sensitive detectors. Ultimately, ...
Spintronics is an emerging field that leverages the spin, or the intrinsic angular momentum, of electrons. By harnessing this quantum-relativistic property, researchers aim to develop devices that store and transmit information ...
