We introduce and motivate the \\emph{dimensional reduction of poles} (DRoP) conjecture, which identifies all collective decay rates of such networks via a connection to waveguides with a one-dimensional topology (e.g. a linear chain of qubits). Using DRoP, we consider many-body effects such as superradiance, subradiance, and bound-states in continuum in multi-dimensional quantum networks. We find that, unlike one-dimensional linear chains, multi-dimensional quantum networks have superradiance in distinct levels, which we call multi-dimensional superradiance. Furthermore, we generalize the $N^{-3}$ scaling of subradiance in a linear chain to $d$-dimensional networks. This work represents the first systematic study of collective behavior in waveguide quantum electrodynamics beyond one-dimensional topologies.", "revisions": [ { "version": "v1", "updated": "2020-03-10T18:00:46.000Z" } ], "analyses": { "keywords": [ "waveguide quantum electrodynamics", "multi-dimensional quantum networks", "subradiance", "collective decay rates", "one-dimensional topology" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
