However, these nonlinear currents are often strictly constrained or forbidden by crystal symmetries, hindering their exploration in a broader range of materials. While the nonlinear photon-drag effect leverages finite photon momentum to circumvent these constraints, its investigation has been largely confined to toy models, lacking a robust numerical framework for realistic materials. Here, we develop a unified microscopic theory of nonlinear photon-drag currents formulated ","authors_text":"Hua Wang, Kai Chang, Likun Shi, Shi Liu, Zhichao Guo, Zhuang Qian, Zhuocheng Lu","cross_cats":["cond-mat.mtrl-sci"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.mes-hall","submitted_at":"2025-11-21T06:51:34Z","title":"Giant Nonlinear Photon-Drag Currents in Moir\\'e Bilayers"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2511.16987","kind":"arxiv","version":2},"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":"sha256:116e6ab07e9ae7576b4e2e93ef1b4ef982c9fd698cdc68ec0249e0fcfe5eafc1","target":"record","created_at":"2026-05-25T02:01:09Z","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":"819203b810446c823b57007bd03f81d6c9dae27b4c798fbf67a08f92bffe6815","cross_cats_sorted":["cond-mat.mtrl-sci"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.mes-hall","submitted_at":"2025-11-21T06:51:34Z","title_canon_sha256":"65aa6528eb3acb795931e5cf2d98e3cf31bdf459be79a52e5df0289c92e08b9c"},"schema_version":"1.0","source":{"id":"2511.16987","kind":"arxiv","version":2}},"canonical_sha256":"e6d899ef3bc191c2b70fc264dd423d8e9b8c5637ad012718eb0d45715596c097","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"e6d899ef3bc191c2b70fc264dd423d8e9b8c5637ad012718eb0d45715596c097","first_computed_at":"2026-05-25T02:01:09.882905Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-25T02:01:09.882905Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"k5xZmEm7lpl+fmVbtkYSDlmB/MF9IhCgbsi+u+ZoNTG7Eyo1w9BEynv8KU/jbeQosFGiI1/FNye0wRWUPp71Ag==","signature_status":"signed_v1","signed_at":"2026-05-25T02:01:09.883372Z","signed_message":"canonical_sha256_bytes"},"source_id":"2511.16987","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:116e6ab07e9ae7576b4e2e93ef1b4ef982c9fd698cdc68ec0249e0fcfe5eafc1","sha256:c73aad9a6a69416ee1f5a76926eea424f7b3586e2e0d1555b0a76c20710a5fb3"],"state_sha256":"e6594aecfeff6c339da1a2c45bb70b282a2de5cd2789e69ec9c6c407d38fc40f"}
