Graphene’s Magic Act Relies on a Small Twist

Carbon is not the shiniest element, nor the most reactive, nor the rarest. But it is one of the most versatile.

Diamonds Shine a Light on Hidden Currents in Graphene

It sounds like pure sorcery: using diamonds to observe invisible power swirling and flowing through carefully crafted channels. But these diamonds are a reality. JQI Fellow Ronald Walsworth and Quantum Technology Center (QTC) Postdoctoral Associate Mark Ku, along with colleagues from several other institutions, including Professor Amir Yacoby and Postdoctoral Fellow Tony Zhou at Harvard, have developed a way to use diamonds to see the elusive details of electrical currents.

Light may unlock a new quantum dance for electrons in graphene

A team of researchers has devised a simple way to tune a hallmark quantum effect in graphene—the material formed from a single layer of carbon atoms—by bathing it in light. Their theoretical work, which was published recently in Physical Review Letters, suggests a way to realize novel quantum behavior that was previously predicted but has so far remained inaccessible in experiments.
