Research reveals exotic quantum states in double-layer graphene

Researchers from Brown and Columbia Universities have demonstrated previously unknown states of matter that arise in double-layer stacks of graphene, a two-dimensional nanomaterial. These new states, known as the fractional quantum Hall effect, arise from the complex interactions of electrons both within and across graphene layers. …

Robocalls Are Overwhelming Hospitals and Patients, Threatening a New Kind of Health Crisis
