For systems with sufficiently low symmetry, the combination of a uniform external field and non-magnetic impurities leads effectively to a random magnetic field which strongly modifies the behavior close to the critical point. Using perturbative renormalization group, we investigate in which regime of the phase diagram the disorder affects critical properties. In heavy fermion systems where even weak disorder can lead to strong fluctuations of the local Kondo temperature, the random fie","authors_text":"Achim Rosch, Fabrizio Anfuso","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.str-el","submitted_at":"2009-01-19T19:51:45Z","title":"Random Field effects in field-driven quantum critical points"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"0901.2881","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":"sha256:896bb59dc113ec1fa086f7155c7da5b0e79429a7dc2318cd1ecf9036f22f56c5","target":"record","created_at":"2026-05-18T02:14:56Z","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":"f75ff52784003856d3a92bfb1b9a09252963335a8ed92db724b632cd926332b2","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.str-el","submitted_at":"2009-01-19T19:51:45Z","title_canon_sha256":"5f5d55e84e045da731636cad724f8bfafd27e5aac98884a0ec8d7b5715f830bd"},"schema_version":"1.0","source":{"id":"0901.2881","kind":"arxiv","version":1}},"canonical_sha256":"09214c5703472811a2437bbc8ed181c73eb9513719b58c6022546a5beb0003cd","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"09214c5703472811a2437bbc8ed181c73eb9513719b58c6022546a5beb0003cd","first_computed_at":"2026-05-18T02:14:56.799437Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T02:14:56.799437Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"DWicTvF21xN8RW+Edt/V0+6IcY4piOmT/NDViBBnqW0FehbJmU9pK5AQI0F0PB/up5ROan0e4F80zb/4+LSuBA==","signature_status":"signed_v1","signed_at":"2026-05-18T02:14:56.800117Z","signed_message":"canonical_sha256_bytes"},"source_id":"0901.2881","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:896bb59dc113ec1fa086f7155c7da5b0e79429a7dc2318cd1ecf9036f22f56c5","sha256:106a7654b45a29affc816834048d2d5d47db58e91a675487eca8e3c58f62a599"],"state_sha256":"17f50814b3f508d47650900a13db855e4c7b333c2315cafb1f21094ef308f007"}
