For dilatation symmetric quantum theories realistic asymptotic cosmology is obtained provided the effective potential has a non-trivial minimum. For theories with dilatation anomaly one needs as a non-trivial \"cosmon condition\" that the energy-momentum tensor in the vacuum is purely anomalous. Such a condition is related to the short-distance renormalization group behavior of the fundamental theory. Observable deviations from the standard hot big bang cosmology are possible.","external_url":"https://arxiv.org/abs/1711.03844","cited_by_count":null,"metadata_source":"pith","metadata_fetched_at":"2026-05-24T01:18:42.311329+00:00","pith_arxiv_id":"1711.03844","created_at":"2026-05-10T07:47:12.097844+00:00","updated_at":"2026-05-24T01:18:42.311329+00:00","title_quality_ok":true,"display_title":"Wetterich, Cosmology and the Fate of Dilatation Sym- metry, Nucl","render_title":"Wetterich, Cosmology and the Fate of Dilatation Sym- metry, Nucl"},"hub":{"state":{"work_id":"3e8dd90f-aa2d-4fea-937a-81bda5ad41a0","tier":"hub","tier_reason":"10+ Pith inbound or 1,000+ external citations","pith_inbound_count":12,"external_cited_by_count":null,"distinct_field_count":4,"first_pith_cited_at":"2024-05-07T01:42:30+00:00","last_pith_cited_at":"2026-05-02T13:35:18+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":"2026-05-30T12:21:12.353042+00:00","tier_text":"hub"},"tier":"hub","role_counts":[{"context_role":"background","n":10},{"context_role":"method","n":1}],"polarity_counts":[{"context_polarity":"background","n":10},{"context_polarity":"use_method","n":1}],"runs":{},"summary":{},"graph":{},"authors":[]}}
