Some classes of models are based on a non-minimal coupling to gravity. These models, which we will call $\\xi$-attractors, describe universal cosmological attractors (including Higgs inflation) and induced inflation models. Another class describes conformal attractors (including Starobinsky inflation and T-models) and their generalization to $\\alpha$-attractors. The aim of this paper is to elucidate the common denominator of these models: their attractor properties stem from a pole of order two in the kinetic term of the inflaton field in the Einstein frame formulation, prior to switching to the canonical variables. We point out that $\\alpha$- and universal attractors differ in the subleading corrections to the kinetic term. As a final step towards unification of $\\xi$ and $\\alpha$ attractors, we introduce a special class of $\\xi$-attractors which is fully equivalent to $\\alpha$-attractors with the identification $\\alpha = 1+{1\\over 6\\xi}$. There is no theoretical lower bound on $r$ in this class of models.","external_url":"https://arxiv.org/abs/1412.3797","cited_by_count":null,"metadata_source":"pith","metadata_fetched_at":"2026-05-24T17:09:43.595327+00:00","pith_arxiv_id":"1412.3797","created_at":"2026-05-10T05:51:09.894921+00:00","updated_at":"2026-06-05T21:23:00.469572+00:00","title_quality_ok":false,"display_title":"The Unity of Cosmological Attractors","render_title":"The Unity of Cosmological Attractors"},"hub":{"state":{"work_id":"3f2be5dc-7424-43db-9516-49f672722bef","tier":"hub","tier_reason":"10+ Pith inbound or 1,000+ external citations","pith_inbound_count":15,"external_cited_by_count":null,"distinct_field_count":4,"first_pith_cited_at":"2018-07-17T04:05:07+00:00","last_pith_cited_at":"2026-05-19T13:18:35+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":"2026-06-10T12:06:32.048916+00:00","tier_text":"hub"},"tier":"hub","role_counts":[{"context_role":"background","n":5}],"polarity_counts":[{"context_polarity":"background","n":5}],"runs":{},"summary":{},"graph":{},"authors":[]}}
