Thermal dynamics and electronic temperature waves in layered correlated materials

Area of Science:

• Condensed Matter Physics
• Thermal Dynamics
• Materials Science

Background:

• Heat transfer at the nanoscale presents significant challenges to conventional thermal dynamics.
• Ultrafast timescales at the nanoscale lead to unconventional phenomena like wave-like temperature propagation.

Purpose of the Study:

• To explore layered strongly correlated materials for controlling electronic heat transfer.
• To identify and understand unconventional heat transfer regimes in these materials.

Main Methods:

• Investigating layered strongly correlated materials.
• Tailoring material properties to control electronic heat transport regimes.
• Analyzing thermal transport from ballistic to diffusive regimes.

Main Results:

• Demonstrated control over a spectrum of electronic heat transport regimes (ballistic, hydrodynamic, diffusive).
• Predicted wave-like temperature oscillations within the hydrodynamic regime up to room temperature.
• Showcased interaction strength as a control parameter for temperature wave dynamics.

Conclusions:

• Layered strongly correlated materials offer a platform for novel thermal management solutions.
• Unconventional heat transfer phenomena, including temperature waves, are achievable at room temperature.
• Precise control over material interactions is key to manipulating nanoscale thermal transport.
