From: Thermal dynamics and electronic temperature waves in layered correlated materials
a Dynamics of the hot-electron population (top) and relative temperature variation of the “cold” electronic population (bottom) recorded on layer n = 15. b Layer profiles of the temperature of the “cold” electronic population (red, left axis) and of the heat flux (blue, right axis) at different instant of times. The blurred yellow band highlights the wave packet of temperature oscillations that follows the ballistic front. c Dynamics of the heat flux (blue, right axis) and temperature gradient of the “cold” electronic population (brown, left axis) on the layer n = 15. Arrows indicates the three regimes of thermal transport discussed in the main text. Panels a and c share the same x-axis. For simplicity the labels are shown only in the x-axis of panel c.
