Rev. Research 2, 043307 (2020)] open a window into the behavior of quantum emitters coupled to a waveguide. Here we develop an approach based on infinite products to study this system theoretically, without the need to approximate the band dispersion relation of the waveguide. We solve the system for a one-dimensional array of one, multiple, and an infinite number of quantum emitters and compare with the experiments. This leads to a detailed characterization of the decay spectrum, with a family of in-gap bound states, mechanisms for enhanced Markovian emission different from superradiance, and the emergence of matter-wave polaritons. info:eu-repo/semantics/openAccess All rights reserved http://www.europeana.eu/rights/rr-f/ 2.9 2022 PHYSICS, ATOMIC, MOLECULAR & CHEMICAL 12 / 35 = 0.343 2022 Q2 T2 OPTICS 44 / 99 = 0.444 2022 Q2 T2 1.11 2022 Atomic and Molecular Physics, and Optics 2022 Q1 5.4 2022 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion Kwon, Joonhyuk Kim, Youngshin Schneble, Dominik 105, 2 (2022), 023703 [10 pp.] Phys. rev., A Physical Review A 2469-9926 6462019 http://zaguan.unizar.es/record/165047/files/texto_completo.pdf Postprint 3140268 http://zaguan.unizar.es/record/165047/files/texto_completo.jpg?subformat=icon icon Postprint oai:zaguan.unizar.es:165047 articulos driver 2026-02-19-09:01:00 ARTICLE
