The description of phonon heat conduction has typically been based on Fourier diffusion
theory. However, over the past three decades, a host of interesting phonon transport …

Classical thermodynamics often helps to passively describe macroscopic heat phenomena
of natural systems, which means people almost cannot change the heat phenomena, but …

Phononic crystals (PnCs) control the transport of sound and heat similar to the control of
electric currents by semiconductors and metals or light by photonic crystals. Basic and …

Thermal transport at the nanoscale level is attracting attention not only because of its
physically interesting features such as the peculiar behavior of phonons due to their …

Recent years have witnessed a much broader use of Brillouin inelastic light-scattering
spectroscopy for the investigation of phonons and magnons in novel materials …

Thermal metamaterials have amazing properties in heat transfer beyond naturally occurring
materials owing to their well-designed artificial structures. The idea of thermal metamaterial …

With the appearance of energy crisis, greenhouse effect, and heat management problem,
the control especially the active and reversible control of heat transport or thermal …

Nonlinear heat transfer can be exploited to reveal novel transport phenomena and thus
enhance people's ability to manipulate heat flux at will. However, there has not been a …

A thermal rectifier/diode is a nonreciprocal element or system that enables preferential heat
transport in one direction. In this work we demonstrate a single-material thermal diode …

Highly efficient absorption of broadband low-frequency sound with a slim subwavelength
meta-structure promises extensive applications in acoustic engineering, which remains a …
