Thermal transport for probing quantum materials

In probing quantum materials, thermal transport is less appreciated than electrical transport. This article aims to show the pivotal role that thermal transport may play in understanding quantum materials—longitudinal thermal transport reflects itinerant quasiparticles, even in an electrical insulating phase, while transverse thermal transport such as the thermal Hall and Nernst effects is

However, it is not clear how this optical analogy persists in nanostructured graphene, for example, with pores.

These limits have been explored in a variety of microdevices ( 14 – 18 ), where it has been shown that, irrespective of the nature of the carriers (phonons, photons, or electrons), heat is ultimately transported via discrete channels. Thermal transport in individual atomic junctions and chains is of great fundamental interest because of the distinctive quantum effects expected to arise in them. By using novel, custom-fabricated, picowatt-resolution calorimetric scanning probes, we measured the thermal conductance of gold and platinum metallic wires down to single-atom junctions. Unfortunately, the experimental study of thermal transport in these systems constitutes a formidable challenge and has remained elusive to date in spite of its fundamental interest (13).
