  • InSb nanoflags are promising for quantum transport studies and surface probe techniques. Here, the authors use scanning gate microscopy on Nb-contacted InSb nanoflag-based Josephson junctions, revealing normal conductance modulation and local supercurrent manipulation, thereby offering a path towards local imaging of the supercurrent flow.

  • The properties of quantum Hall states can be probed in experiments inspired by optical interferometers. Now, a device design that overcomes major drawbacks of existing interferometers allows the extraction of the quasiparticle statistics.

  • Direct imaging and characterization of propagating plasmons in high-quality graphene, encapsulated between two films of hexagonal boron nitride, has now been achieved together with the observation of very low plasmon damping.

  • Magnons are collective spin excitations that can propagate over long distances — an attractive trait for information-transfer technologies — but we need to better understand their thermodynamic properties. A platform using graphene may hold the key.

  • Quantum Hall systems represent an example of topological quantum matter, where quasiparticles with fractional statistics (anyons) may emerge. This Technical Review presents a survey of recent developments in quantum Hall interferometry.
