M\"obius-like Real-Space Topology Reshapes Spectral Winding Topology in Hatano-Nelson Rings
new Abstract: The spectral winding number serves as a bulk topological invariant in non-Hermitian systems, governing the emergence of skin modes and encoding the non-Hermitian bulk-boundary correspondence. However, most existing studies are built on conventional lattice geometries such as linear chains, rings, or planar arrays, leaving the role of real-space topological connectivity as an independent degree of freedom largely unexplored. Here, we construct a M\"obius ring system by cutting...
