Integrated optoelectronic devices, with electrons and photons as energy and information carriers, dominate current daily life and industrial development. However, electron- and photon-based devices ...

You can’t divide the indivisible, unless you use quantum mechanics. Physicists have now turned to quantum effects to split phonons, the smallest bits of sound, researchers report in the June 9 Science ...

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 ...

Active tuning of anisotropic phonon polaritons in natural van der Waals crystals with negative permittivity substrates and its application in energy transport Manipulating photons on the nanoscale to ...

This makes phonon-polaritons ideal for high-tech applications like sub-wavelength imaging, molecular sensors, and heat management within electronics. However, research on phonon-polariton waves has ...

A tiny, levitated bead is at the core of an unprecedentedly bright laser that shoots particles of sound instead of light. Just as a ray of light is made up of many particles called photons, sound ...

Andrew N. Cleland receives funding from various US federal funding agencies. He is a fellow of the American Physical Society (APS) and the American Association for the Advancement of Science. He is ...
