Phonons, quasiparticles in a crystal lattice that are usually hard to control by external fields, can be manipulated by a magnetic field -- but it takes a very strong magnet. Phonons are collective ...

Materials consisting of a few atomic layers display properties determined by quantum physics. In a stack of such layers, vibrations of the atoms can be triggered by infrared light. New experimental ...

A new hollow optical fiber greatly reduces the "noise" interfering with the signals it transmits compared to the single-mode fibers now widely used, researchers at the University of Rochester report.

Experiments show that carbon nanotubes transfer heat inefficiently at small scales, raising concerns for cooling and performance in nanoelectronic devices. (Nanowerk Spotlight) Thermal energy in solid ...

HOUSTON – (Feb. 15, 2022) – Phonons are collective atomic vibrations, or quasiparticles, that act as the main heat carriers in a crystal lattice. Under certain circumstances, their properties can be ...
