This study presents a robust experimental protocol for realizing non-Hermitian topological phases using Rydberg atom arrays with synthetic gauge fields. By engineering dissipative channels to induce skin effects, the research demonstrates that these quantum phenomena remain stable against parameter fluctuations in neutral-atom simulators. The work advances practical open-system quantum simulation capabilities specifically tailored for exploring complex NH topology without relying on superconducting qubits or photonic platforms.
Engineering the non-Hermitian Su-Schrieffer-Heeger model with skin effects in Rydberg atom arrays
arXiv:2601.20114v3 Announce Type: replace Abstract: We propose and systematically analyze a practical scheme for implementing a one-dimensional non-Hermitian (NH) Su-Schrieffer-Heeger model using individually addressable Rydberg atom arrays. Our setup consists of an atomic chain with three-atom unit cells, in which a synthetic gauge field is generated by applying multicolor laser fields. By engineering fast dissipative channels for one auxiliary atom in each unit cell, adiabatic elimination effectively gives rise to a NH skin effect. We examine how fluctuations in the experimental parameters influence both the skin effect and the topological invariant in real space and find that both features remain highly robust. This work establishes a versatile, controllable, and programmable open-system quantum simulator with neutral atoms, providing a clear route for exploring rich NH topological phenomena.
