2026-07-03 The data of the article"Tunable Single-Photon Scattering and Reflection Nonreciprocity in Topological Giant Atom–Waveguide Coupled Systems" doi:10.57760/sciencedb.j00213.00266 en This dataset is the supporting data for the study of single photon scattering in a one-dimensional waveguide system coupled with topological giant atoms. It mainly includes SSH chain energy spectrum data, system reflectivity data, reflection non reciprocity data, and reflectivity data under disordered conditions. The data content covers the original data used for the main numerical images in the article, and can be used to reproduce the reflectance spectra, energy spectra, and reflectance non reciprocity images under different parameter conditions. The relevant parameters include the coupling strength ratio between SSH chains, detuning, cumulative phase, number of atoms, atomic dissipation rate, and different types of disordered disturbances. The reflectance data in this dataset mainly corresponds to the single photon scattering results without dissipation, and is used to demonstrate the influence of SSH chain topology phase, cumulative phase, and atomic number on the reflectance spectrum structure; Disordered data is used to compare the changes in reflectance spectra under ordered and disordered conditions; The reflection non reciprocity data corresponds to the results of atomic dissipation and asymmetric waveguide coupling strength at both ends, used to analyze the regulatory effects of atomic dissipation rate, topological parameters, and cumulative phase on reflection non reciprocity. Through these data, the main images in the article can be checked, reproduced, and further analyzed. This dataset mainly consists of the following nine files. File 1 mainly contains data on the variation of reflectance with detuning when the system is in different topological phases ("data of R vs Delta J1 curves,. dat"; Origin), corresponding to Figure 2 (b) and Figure 2 (c) in this article. File 2 mainly contains two-dimensional data ("data of R vs Delta J1 spectrum,. dat/. opju"; Origin) on the variation of reflectance with detuning and the ratio of intracellular and intercellular coupling strength, corresponding to Figure 2 (a) in this article. File 3 mainly contains data on the variation of reflectance with detuning under different cumulative phases when the system is in two topological phases ("data of R vs Delta theta curves,. dat"; Origin), corresponding to Figures 3 (b) -3 (e) and 3 (g) -3 (j) in this article. File 4 mainly contains two-dimensional data ("data of R vs Delta theta spectrum,. dat/. opju"; Origin) on the variation of reflectance with detuning and cumulative phase when the system is in two topological phases, corresponding to Figure 3 (a) and Figure 3 (f) in this article. File 5 mainly contains the energy spectrum data of the SSH chain ("data of SSH spectrum,. dat/. opju/. nb"; Origin/Mathematica), corresponding to Figure 1 (b) in this article. File 6 mainly contains data on the variation of reflectivity with detuning under different numbers of atoms ("different N,. opju"; Origin), corresponding to Figure 4 in this article. File 7 mainly contains reflectance data under three disordered conditions ("disorder,. dat"; Origin), corresponding to Figure 5 in this article. File 8 mainly contains data on the variation of reflection non reciprocity with atomic dissipation rate and the ratio of intracellular and intercellular coupling strength ("I vs gamma J1,. opju"; Origin), corresponding to Figure 6 in this article. File 9 mainly contains data on the variation of reflection non reciprocity with atomic dissipation rate and cumulative phase ("I vs gamma theta,. opju"; Origin), corresponding to Figure 7 in this article.  Waveguide-QED; topological giant atom; single-photon scattering; nonreciprocity zhu yan feng Zhang Yuqing Peng Zhaohui Quan Haiyan Ji Beibei Fu Xiangyun Zhu Zhonghua Tan Lei PUBLIC https://creativecommons.org/licenses/by/4.0/ dataset http://www.doi.org/10.7498/aps.75.20260530 Science Data Bank
