Graphene provides a rich platform to study many-body effects, owing to its massless chiral charge carriers and the fourfold degeneracy arising from their spin and valley degrees of freedom. Graduate student Ben Feldman, Prof. Amir Yacoby, and colleagues from Max-Planck-Institut in Stuttgart used a scanning single-electron transistor to measure the local electronic compressibility of suspended graphene, and observed an unusual pattern of incompressible fractional quantum Hall states that follows the standard composite fermion sequence between filling factors ν = 0 and 1 but involves only even-numerator fractions between ν = 1 and 2.

The fundamental properties of light derive from its constituent particles - massless quanta (photons) that do not interact with one another. However, it has long been known that the realization of coherent interactions between individual photons, akin to those associated with conventional massive particles, could enable a wide variety of novel scientific and engineering applications.
