The transport of phonons, which are the dominant heat carriers in non-metallic solids, is usually diffusive and describable by Fourier’s law of heat conduction. Regimes where Fourier’s law breaks down ...

Researchers have introduced an innovative two-step excitation approach that makes it possible to efficiently generate and clearly separate different modes of hyperbolic polaritons. An international co ...

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 ...

New research has uncovered a novel way to combine two different states of matter. For one of the first times, topological photons -- light -- has been combined with lattice vibrations, also known as ...

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 in the UK and Russia have revived concepts first put forth in the 1940s to develop a new theory of the heat capacity of liquids. Created by Dima Bolmatov and Kostya Trachenko of Queen Mary, ...

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 ...
