Hot nanostructures cool faster when they are physically close together

A complete description of nanoscale thermal transport is a fundamental problem that has defied understanding for decades. Here, researchers uncover a new regime of thermal transport near nanoscale structures, where counterintuitively, nanoscale hot spots cool more quickly when placed close together than when they are widely separated.
