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.

What had long been considered as a vision of the future is now a reality – devices can detect their surroundings as if they were human senses and interact with them. Sensors close the gap to the digital world. Combined with appropriate software, smart devices and robots, for example, can see, hear, smell or feel and above all “intuitively understand” their environment, thereby simplifying our lives. The decisive factor here is the interpretation and linking of information from different sensors.
