Furthermore, approximate shift symmetries of the system naturally control corrections to the axion potential. This suggests a general mechanism for chaotic inflation driven by monodromy-extended closed-string axions. We systematically analyze this possibility and show that the mechanism is compatible with moduli stabilization and can be realized in many types of compactifications, including warped Calabi-Yau manifolds and more general Ricci-curved spaces. In this broad class of models, the potential is linear in the canonical inflaton field, predicting a tensor to scalar ratio r=0.07 accessible to upcoming cosmic microwave background (CMB) observations.","external_url":"https://arxiv.org/abs/0808.0706","cited_by_count":null,"metadata_source":"pith","metadata_fetched_at":"2026-05-24T23:55:06.743045+00:00","pith_arxiv_id":"0808.0706","created_at":"2026-05-10T10:34:29.172252+00:00","updated_at":"2026-05-24T23:55:06.743045+00:00","title_quality_ok":true,"display_title":"McAllister, E","render_title":"McAllister, E"},"hub":{"state":{"work_id":"816a01f7-e7f4-43d6-bf48-99c0d3cc99cd","tier":"hub","tier_reason":"10+ Pith inbound or 1,000+ external citations","pith_inbound_count":14,"external_cited_by_count":null,"distinct_field_count":5,"first_pith_cited_at":"2009-05-28T19:38:46+00:00","last_pith_cited_at":"2026-05-20T12:24:00+00:00","author_build_status":"not_needed","summary_status":"needed","contexts_status":"needed","graph_status":"needed","ask_index_status":"not_needed","reader_status":"not_needed","recognition_status":"not_needed","updated_at":"2026-06-05T15:49:10.556269+00:00","tier_text":"hub"},"tier":"hub","role_counts":[{"context_role":"background","n":11}],"polarity_counts":[{"context_polarity":"background","n":9},{"context_polarity":"support","n":1},{"context_polarity":"unclear","n":1}],"runs":{},"summary":{},"graph":{},"authors":[]}}
