For two centuries, engineers have trusted a simple rule to predict how heat flows through solids, from jet-engine blades to smartphone chips. Now a set of carefully designed experiments has revealed a ...

Artistic visualization of a crystalline rod made of the semimetal ZrTe 5. There is a heat gradient from one end to the other. In its center, giant oscillations in its heat conduction are toggled by ...

The article discusses how increasing disorder in the atomic structure of materials influences macroscopic heat conduction — a critical property for heat-management technologies. The materials studied ...
