Robust Superradiance and Spontaneous Spin Ordering in Disordered Waveguide Quantum Electrodynamics

Daniel Malz, Peter Rabl, Xin H. H. Zhang

The hallmark N squared scaling of superradiant emission remains asymptotically robust to strong spatial and spectral disorder in a one-dimensional waveguide.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

the key signature of superradiance remains asymptotically robust under strong spatial and spectral disorder, but also exhibits subtle finite-size scaling toward this limit

C2weakest assumption

The semiclassical approximation used in the large-scale simulations accurately captures the collective decay dynamics even under strong disorder, without significant quantum corrections that would alter the observed robustness or ordering.

C3one line summary

Superradiant emission remains asymptotically robust to strong disorder in waveguide QED arrays because atoms spontaneously self-organize their spin states to optimize constructive interference.
