Researcher construct invisibility cloak for thermal flow

By means of special metamaterials, light and sound can be passed around objects. KIT researchers now succeeded in demonstrating that the same materials can also be used to specifically influence the propagation of heat. A structured plate of copper and silicon conducts heat around a central area without the edge being affected.

Quantum optics with microwaves

Physicists at ETH Zurich have demonstrated one of the quintessential effects of quantum optics - known as the Hong-Ou-Mandel effect - with microwaves, whose frequency is 100000 times lower than that of visible light. The experiment takes quantum optics into a new frequency regime and could eventually lead to new technological applications.
