  • The structure of domain walls is of interest to the antiferromagnetic spintronics. Here the authors find an additional contribution to the Hall conductivity tensor and a transverse magnetization generated by domain walls in Mn3Sn and report that the sign of this contribution depends on the prior history of the sample.

  • Non-Hermitian systems can be described in terms of gain and loss with a coupled environment—a hard feature to tune in quantum devices. Now an experiment shows non-Hermitian topology in a quantum Hall ring without relying on gain and loss.

  • Edge-magnetoplasmon interferometers have been proposed as a tool to investigate anyonic properties of quasiparticles in the regime of the Fractional Quantum Hall effect. In this work, the authors demonstrate the possibility to control electrostatically the resonance frequency of EMP resonators of micrometric size and explain the role of gates, paving the way toward the realization of anyonic interferometers.
