Recently, Kitaev has found that the SYK model is maximally chaotic and has proposed it as a model of holography. We solve the Schwinger-Dyson equation and compute the spectrum of two-particle states in SYK, finding both a continuous and discrete tower. The four-point function is expressed as a sum over the spectrum. The sum over the discrete tower is evaluated.","external_url":"https://arxiv.org/abs/1601.06768","cited_by_count":null,"metadata_source":"pith","metadata_fetched_at":"2026-05-25T01:25:10.722857+00:00","pith_arxiv_id":"1601.06768","created_at":"2026-05-10T11:10:09.362544+00:00","updated_at":"2026-05-25T01:25:10.722857+00:00","title_quality_ok":true,"display_title":"Polchinski and V","render_title":"Polchinski and V"},"hub":{"state":{"work_id":"dda4b709-b00c-447f-a5fa-a1989dc89376","tier":"hub","tier_reason":"10+ Pith inbound or 1,000+ external citations","pith_inbound_count":10,"external_cited_by_count":null,"distinct_field_count":3,"first_pith_cited_at":"2019-07-08T11:59:43+00:00","last_pith_cited_at":"2026-04-28T18:00:03+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":"2026-05-26T14:56:45.415258+00:00","tier_text":"hub"},"tier":"hub","role_counts":[{"context_role":"background","n":7}],"polarity_counts":[{"context_polarity":"background","n":6},{"context_polarity":"unclear","n":1}],"runs":{},"summary":{},"graph":{},"authors":[]}}
