In particular, the frustrated coupling between waveguide modes in a kagome array leads to a dispersionless flat band consisting of spatially localized modes. Here we propose a complex photonic lattice by placing $\\mathcal{PT}$-symmetric dimers at the kagome lattice points. Each dimer corresponds to a pair of strongly coupled waveguides. With balanced arrangement of gain and loss on individual dimers, the system exhibits a $\\mathcal{PT}$-symmetric phase for finite gain/l","authors_text":"Avadh Saxena, Gia-Wei Chern","cross_cats":["cond-mat.other"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.optics","submitted_at":"2015-09-18T22:26:15Z","title":"PT-symmetric phase in kagome photonic lattices"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1509.05813","kind":"arxiv","version":1},"verdict":{"created_at":null,"id":null,"model_set":{},"one_line_summary":"","pipeline_version":null,"pith_extraction_headline":"","strongest_claim":"","weakest_assumption":""}},"verdict_id":null}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:5b1c05d3c4c6d1835d62cfbb71627b3bd8b8c0feec3ae4f556a779b90f52938d","target":"record","created_at":"2026-05-18T01:24:32Z","signer":{"key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signer_id":"pith.science","signer_type":"pith_registry"},"payload":{"attestation_state":"computed","canonical_record":{"metadata":{"abstract_canon_sha256":"259ae076f27d2b57b43a0a697d39d2f63c01223e9b23b3b19526501e57e45607","cross_cats_sorted":["cond-mat.other"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.optics","submitted_at":"2015-09-18T22:26:15Z","title_canon_sha256":"f2c0df81bf7fdb1a3d95d3d54c51c3e1449379c7eb674e8709367df6fcc9ef09"},"schema_version":"1.0","source":{"id":"1509.05813","kind":"arxiv","version":1}},"canonical_sha256":"62e10e1ffe7928d906eef2ee27f13640d226a1a8c07610c30e9c44865ed143ed","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"62e10e1ffe7928d906eef2ee27f13640d226a1a8c07610c30e9c44865ed143ed","first_computed_at":"2026-05-18T01:24:32.715117Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T01:24:32.715117Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"Hdw1fLUOkCekWcUxNrWxdDnZK6u6fuPRHfezxkogNaHs7wFSXvWXPlLkhuXp39QveKjC+tjqqQSUJGynN+GyBg==","signature_status":"signed_v1","signed_at":"2026-05-18T01:24:32.715740Z","signed_message":"canonical_sha256_bytes"},"source_id":"1509.05813","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:5b1c05d3c4c6d1835d62cfbb71627b3bd8b8c0feec3ae4f556a779b90f52938d","sha256:66b55e3d5a6a15659153b66cc40b87cf863f898b5a5cbbf63d3b5ec193cd973e"],"state_sha256":"a84042f608597c2866c0c12626208c65ac1d28b815362607da4801a3a34ee0e1"}
