Non-pertubative expressions in B are given for the magneto-optical effects and optical anisotropy. We then consider the multiple scattering regime and address the fate of the coherent backscattering (CBS) effect. We show that, for atoms with nonzero spin in their ground state, the CBS interference contrast can be increased compared to its value when B=0, a","authors_text":"Christian Miniatura, Dominique Delande, Guillaume Labeyrie, Olivier Sigwarth","cross_cats":["cond-mat.quant-gas","quant-ph"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.atom-ph","submitted_at":"2013-03-28T20:36:55Z","title":"Multiple scattering of light in cold atomic clouds with a magnetic field"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1303.7249","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":"sha256:10b94100c9f79ed8ec509ddac0271cd7396a7a9024e4860d4c8de588727bf2d8","target":"record","created_at":"2026-05-18T01:50:51Z","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":"314faba1849f6d0a2d17a3820efe2d2007a08789978fbddd434428b5ec37cc5e","cross_cats_sorted":["cond-mat.quant-gas","quant-ph"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.atom-ph","submitted_at":"2013-03-28T20:36:55Z","title_canon_sha256":"a38552432fadd1d648587eefbef02b7ab181c641c8c8591dcc99c5f291748896"},"schema_version":"1.0","source":{"id":"1303.7249","kind":"arxiv","version":1}},"canonical_sha256":"87109380d06aa8f1dec5887af462c57a7b1fd3625c74404a8ef24c3b409771f1","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"87109380d06aa8f1dec5887af462c57a7b1fd3625c74404a8ef24c3b409771f1","first_computed_at":"2026-05-18T01:50:51.326574Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T01:50:51.326574Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"v+0sxZaU/hRumWYmxXvxlBfAgVYn2EE6XXjjcysDIHY3VQxP6YRPYUSZC0yywHUtdoNBG967YjA47A7uLrxHCg==","signature_status":"signed_v1","signed_at":"2026-05-18T01:50:51.327216Z","signed_message":"canonical_sha256_bytes"},"source_id":"1303.7249","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:10b94100c9f79ed8ec509ddac0271cd7396a7a9024e4860d4c8de588727bf2d8","sha256:4d5a9969544efdb222b4d1f9bb3b9031108e89a5c1b5215769221bf34fcc1065"],"state_sha256":"c893a2ee733441409d90725170c35feb38505d3746e6acda1199e7273593762b"}
