Acoustic frequency combs organize sound or mechanical vibrations into a series of evenly spaced frequencies, much like the ...

WEST LAFAYETTE, Ind. – New findings have solved a longstanding obstacle in research to understand the effects of heat conduction in solid materials, a critical issue in many applications, from energy ...

A new study published in Nature Physics introduces a theory of electron-phonon coupling that is affected by the quantum geometry of the electronic wavefunctions. The movement of electrons in a lattice ...

Rochester researchers are trapping nanoparticle-sized silica beads in an optical tweezer in a series of experiments that could shed new light on the fundamental properties of lasers – and perhaps lead ...

Add Yahoo as a preferred source to see more of our stories on Google. Researchers at Rice University and their collaborators have achieved a groundbreaking demonstration of strong interference between ...

Scientists have observed, quantified and created a new theoretical model of the coupling of two forms of collective atomic excitation, known as magnons and phonons in crystals of the antiferromagnet ...

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 ...

Physicists have developed a new technique to probe elementary quantum excitations of atomic vibrations inside a diamond crystal under ambient conditions. The technique uses ultra-short laser pulses ...

(a) Phonon (wavy lines) absorption and (b) stimulated emission of so called longitudinal optical (LO) phonons schematically explained in the conduction band structure (black parabola: electron energy ...

An Osaka Metropolitan University-led research team investigated the decay time of coherent longitudinal optical (LO) phonons both in a GaAs1−xNx epilayer and in a GaAs single crystal to clarify the ...
