Heat transport in the quantum regime has its own limits !

At extremely low temperature, the transport of matter, charge or energy through a very narrow "quasi one-dimensional" channel can be quantized. This has been demonstrated for a long time, for example for a current of electrical charges. Indeed, electrical conductance across a quantum dot takes values that are an integer multiple of the quantum of electrical conductance 2e2 /h, where e is the charge of the electron and h is the Planck constant. We expect to observe the same quantization phenomenon for heat currents, a regime that would no longer follow Fourier’s law, the classical law of heat conduction. As this quantization has been shown clearly for electrons and photons, it remains a mystery for phonons, the quanta of vibration of the crystal lattice. Full text.

Thermal energy harvesting on a chip : toward autonomous sensors

The measurement of very tiny quantities of heat is essential for a deep understanding of thermal transfer in nanostructures. Fundamental research on "nanothermal" physics, carried out over ten years at the Institut Néel has now given rise to a disruptive technology for harvesting thermal energy at the nanometre scale.
