A study published in Nature Physics reports a method to guide heat using photons at room temperature, which could improve thermal management in quantum electronics.
Key Details
- Researchers introduced a novel method for heat management using photon focusing, a technique previously limited to cryogenic temperatures.
- The experiment utilized boron arsenide to steer photons along a defined path, with heat traveling along the same path.
- This is the first observation of photon focusing at room temperature.
Background
- As electronics shrink with quantum technology, heat density increases, creating a need for better thermal management.
- The study aims to address the challenge of controlling heat at different temperatures in quantum systems.
“This is a fundamental observation that enables us to think about thermal management in a new way.”
