Quantum scars make their mark in graphene (nature.com)
By patterning an ultrathin layered structure with tiny wells, physicists have created and imaged peculiar states known as quantum scars — revealing behaviour that could be used to boost the performance of electronic devices.

Revealing the superconducting limit of twisted bilayer graphene (phys.org)
Graphene is a simple material containing only a single layer of carbon atoms, but when two sheets of it are stacked together and offset at a slight angle, this twisted bilayer material produces numerous intriguing effects, notably superconductivity.
