Symposium QN04-Nanoscale Heat Transport—Fundamentals

The length scales of continuously shrinking nanoscale materials and devices have nowadays become comparable to those of their relevant energy carriers e.g. phonons, electrons, magnons, and photons. This opens up numerous opportunities for nanoscale control and manipulation of thermal transport processes, and attaining radically improved or completely new thermal functionalities. However, heat transport in nanoscale materials and at their interfaces remains poorly understood, even for crystalline materials. There is much work to be done to fully characterize and rationalize departures from the Fourier law or the breakdown of heat carriers, in order to understand and control novel heat transport regimes (e.g. quasi-ballistic or superdiffusive, localized, hydrodynamic, coherent, incoherent, strongly anharmonic). Thermal transport mechanisms in disordered and amorphous materials, soft and biological matter, liquids and their interfaces are even more challenging to understand and manipulate. Interactions among different types of heat carriers and their impact on nanoscale thermal transport processes are another topic of increasing interest, as well as out-of-equilibrium heat transport phenomena. This symposium will highlight recent significant developments in the experimental, theoretical, and computational techniques that address the challenges described above, and showcase novel proposals of controlling heat transport mechanisms.

Topics will include:

  • Nanoscale heat transport phenomena (e.g. quasi-ballistic transport, localization)
  • Thermal transport at interfaces
  • Thermal transport in disordered and amorphous materials
  • Thermal transport in liquids and soft and biological matter
  • Near-field thermal radiation, phononics and metamaterials
  • Non-equilibrium and picosecond thermal transient behaviors
  • Thermal transport characterization techniques (e.g. mean-free path spectroscopies)
  • Phonon and magnon imaging (e.g. neutron, Brillouin, X-ray scattering) and thermal imaging
  • New formalisms or simulation techniques of thermal transport
  • Interactions among different types of energy carriers (e.g. phonons, electrons, magnons, photons)
  • A tutorial complementing this symposium is tentatively planned.
