Summary

We propose to study several novel ways to control and strongly modify heat flow, using nanoscale devices such as phononic crystals and phononic glass, topological phononic metamaterials and phonon tunnel junctions. The effects to demonstrate and exploit are i) localization of heat flow with disorder, ii) electrical control of phonon heat flow, iii) tunnelling of phonons across vacuum gaps and iv) dissipationless topological edge modes. We expect to see orders of magnitude reduction or enhancement of heat flow, as well as guiding, filtering and rectification of phononic heat transport at low temperatures. Possible applications range from improved performance of ultrasensitive radiation detectors to heat dissipation management of quantum processors to energy harvesting from waste heat.
