We've got another notable first in the field of physics to report: A specific type of quantum behavior in waves of heat has now been observed at room temperature, rather than at the ultra-low cryogenic temperatures that are usually required.
The quantum behavior is phonon focusing, which is where atomic-level, heat-carrying vibrations (the quantum packets known as phonons) travel through a non-metallic material in specific patterns, like rays from a star.
Crucially, this is different from the standard behavior of heat-transporting phonons at room temperature, where the heat spreads out evenly in all directions (a classical rather than quantum way of moving).
It means, potentially, that we can control heat much more precisely in next-generation, quantum-level electronics, and overcome previous bottlenecks. The experiment and observations have been reported in Nature Physics by a team from the University of California, Los Angeles.
