Quantum-limit phenomena and band structure in the magnetic topological semimetal EuZn2As2
Rongying Jin

Communications Physics, Published online: 16 September 2023; doi:10.1038/s42005-023-01378-8

The interplay between magnetism and non-trivial topological band structures in magnetic topological insulators can give rise to further exotic physical phenomenon. Here, the authors investigate the magnetic and electronic properties of EuZn2As2 under high-magnetic fields and low-temperatures and discuss what the observations can tell us about the interplay between magnetism and electronic topology in this system.

Deep learning enabled topological design of exceptional points for multi-optical-parameter control
Changzhi Gu

Communications Physics, Published online: 16 September 2023; doi:10.1038/s42005-023-01380-0

Exceptional points (EPs) with inherent polarization decoupling, amplitude and wavelength modulation properties, provide a tool for multi-optical-parameter modulation. Leveraging deep learning, the authors observe topological charge conservation and utilize the topologically protected optical parameter distribution around EPs to introduce two kinds of multifunctional optical devices.
