Time-modulated near-field radiative heat transfer
Renwen Yu, Shanhui Fan
We explore near-field radiative heat transfer between two bodies under time modulation by developing a rigorous fluctuational electrodynamics formalism. We demonstrate that time mo…

Tracking ultrafast hot-electron diffusion in space and time by ultrafast thermo-modulation microscopy
Alexander Block, Matz Liebel, Renwen Yu +4
The ultrafast response of metals to light is governed by intriguing non-equilibrium dynamics involving the interplay of excited electrons and phonons. The coupling between them giv…
