Heat conduction originates from both particle-like diffusion of phonon wave-packets (blurred spheres, following the realistic 3D phonon dispersion of CsPbBr3) and wave-like tunneling (blue waves).

How heat travels, matters. Yet, there is still no consensus on the exact physical mechanism that causes anomalous heat conduction -- despite the existence of previous numerical simulation, theoretical ...

In many quantum materials—materials with unusual electrical and magnetic properties driven by quantum mechanical effects—electrons can organize themselves into Landau levels. Landau levels are ...

Thermal conduction is the transfer of internal energy by microscopic collisions of particles and movement of electrons within a body. The colliding particles, which include molecules, atoms and ...

Heat and mass ransfer by heat conduction, diffusion, and convection. (Linear phenomena only; heat transfer by radiation, natural convection, and mass transfer in concentrated solutions are not ...

When designing electronics, heat dissipated to the surroundings by micro devices is an important consideration because heat has a powerful and stringent effect on their operation and lifespan. When an ...
