Interference-Protected Subradiance and Bound States in Nested Atomic Arrays

Quantum Physics [Submitted on 11 Apr 2026] Interference-Protected Subradiance and Bound States in Nested Atomic Arrays Bella Santosa, Daniel Leykam Collective subradiant states in waveguide QED are highly sensitive to disorder, limiting their scalability and robustness. We propose a deterministic approach to engineering atom arrays based on a Minkowski sum construction, generating quasi-disordered structures with built-in correlations. This leads to mode-selective radiative coupling: interactions between dark modes are parametrically suppressed, while bright modes can hybridize. We study the stability of these subradiant and bound-state-like modes against moderate positional disorder. Our work provides a route to robust, analytically controllable subradiance through engineered quasi-disorder, with direct relevance to atom-waveguide and circuit QED experiments.
