Abstract

Scale invariance is a common property of our everyday environment. Its
breaking gives rise to less common but beautiful structures like fractals.
At the quantum level, breaking of continuous scale invariance is a
remarkable exemple of quantum phase transition also known as scale
anomaly. The general features of this transition will be presented at an
elementary quantum mechanics level. Then, we will show recent experimental
evidence of this transition in graphene.
