Non-Hermitian higher-order topological insulators enabled by altermagnet engineering

This article reports on research related to non-Hermitian higher-order topological insulators, a complex topic in condensed matter physics. The use of 'altermagnet engineering' suggests a novel approach to manipulating these materials. The source being ArXiv indicates this is a pre-print, meaning it's likely a recent research finding awaiting peer review. The title is technical and targeted towards a specialized audience.
