Controlling acoustic transport in hypersonic crystals
Center for Nanoscale Materials users from Toyota Research Institute of North America, working with CNM's Nanophotonics Group, have determined that bulk coherent acoustic vibrations are heavily damped by scattering from radially ...

An optomechanical crystal to study interactions among colocalized photons and phonons
A photon is the quantum particle of light and electromagnetic radiation. A phonon is its equivalent when it comes to mechanical vibrations of matter and heat transmission. Although it might seem surprising, electromagnetic ...

Thermal conductance can be controlled like waves using nanostructures
Thermal conduction is a familiar everyday phenomenon. In a hot sauna, for instance, you can sit comfortably on a wooden bench that has a temperature of 100C (212F), but if you touch a metallic nail with the same temperature, ...

Tiny tool measures heat at the nanoscale
How heat flows at the nanoscale can be very different than at larger scales. Understanding how surfaces affect the transport of the fundamental units of heat, called phonons, could impact everything from thermoelectric materials ...

Crossover sound: Unambiguous evidence for coherent phonons in superlattices
We all learn in high school science about the dual nature of light - that it exists as both waves and quantum particles called photons. It is this duality of light that enables the coherent transport of photons in lasers. ...

Controllable mode competition in a phonon laser
Using a novel realization of a "phonon laser," scientists at PML and the Joint Quantum Institute (JQI) have observed and learned to control a process called mode competition. This process occurs routinely in optical lasers, ...
