Experiment shows Einstein’s quantum ‘spooky action’ approaches the human scale – The Conversation AU

The Conversation AUExperiment shows Einstein's quantum 'spooky action' approaches the human scaleThe Conversation AUQuantum physics is often defined as the physics of the very small – think atoms, electrons and photons. But we have managed to demonstrate one of the quirky features of quantum physics at a much larger scale. In a paper published today in Nature, we …

Turning graphene into light nanosensors

Graphene has many properties, but it does not absorb light very well. To remedy this, physicists resort to embedding a sheet of graphene in a flat photonic crystal. Scientists now demonstrate that by altering the temperature in such a hybrid cavity structure, they can tune its capacity for optical absorption. This means graphene-based nano-devices could potentially be used as temperature-sensitive sensors.
