We find that the transmitance decays exponentially as a function of the system size, with an enhanced rate $\\xi_{\\gamma}(W)^{-1}=\\xi_0(W)^{-1}+\\xi_{\\gamma} (0)^{-1}$, where $\\xi_0(W)$ is the localization length of the equivalent passive random medium and $\\xi_{\\gamma}(0)$ is the attenuation/amplification length of the corresponding perfect system with a ${\\cal PT}$-symmetric refraction index profile. While transmitance processes are reciprocal"},"claims":{"count":0,"items":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1205.1849","kind":"arxiv","version":1},"verdict":{"id":null,"model_set":{},"created_at":null,"strongest_claim":"","one_line_summary":"","pipeline_version":null,"weakest_assumption":"","pith_extraction_headline":""},"references":{"count":0,"sample":[],"resolved_work":0,"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57","internal_anchors":0},"formal_canon":{"evidence_count":0,"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"author_claims":{"count":0,"strong_count":0,"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"builder_version":"pith-number-builder-2026-05-17-v1"}
