Every von Neumann algebra that is not a factor admits a canonical decomposition into factors [47, 74]. Thus, the general classification problem reduces to the study of factors, which are exhaustively classified into type I, type II, and type III.

However, this does not by itself guarantee that it captures finer effects beyond the fixed-area regime at leading order in 1/G N. Moreover, when interpreted as a holographic error-correcting code, it has trivial area operators [18]. More generally, if one wishes to move closer to gravitational systems, it is natural to consider ingredients such as gauge redundancy and global constraints, which are closely tied to diffeomorphism invariance. In such settings, Hilbert-space factorization can be subtle, and additional structures such as Gauss-law constraints and boundary superselection sectors may become relevant."},{"citing_arxiv_id":"2512.19452","ref_index":27,"ref_count":1,"confidence":0.98,"is_internal_anchor":true,"paper_title":"Holographic Tensor Networks as Tessellations of Geometry","primary_cat":"hep-th","submitted_at":"2025-12-22T14:57:18+00:00","verdict":"UNVERDICTED","verdict_confidence":"LOW","novelty_score":6.0,"formal_verification":"none","one_line_summary":"Holographic tensor networks constructed from PEE-thread tessellations of AdS geometry reproduce the exact Ryu-Takayanagi formula in factorized EPR, perfect-tensor, and random variants.","context_count":0,"top_context_role":null,"top_context_polarity":null,"context_text":null},{"citing_arxiv_id":"2512.11754","ref_index":9,"ref_count":1,"confidence":0.98,"is_internal_anchor":true,"paper_title":"Modular Witten Diagrams and Quantum Extremality","primary_cat":"hep-th","submitted_at":"2025-12-12T18:05:09+00:00","verdict":"UNVERDICTED","verdict_confidence":"LOW","novelty_score":6.0,"formal_verification":"none","one_line_summary":"Modular Witten diagrams reproduce the O(λ² G_N) correction to holographic entanglement entropy, matching the canonical energy term in the quantum Ryu-Takayanagi formula with wedge shape deformation.","context_count":0,"top_context_role":null,"top_context_polarity":null,"context_text":null},{"citing_arxiv_id":"2511.01978","ref_index":77,"ref_count":1,"confidence":0.98,"is_internal_anchor":true,"paper_title":"Single-Sided Black Holes in Double-Scaled SYK Model and No Man's Island","primary_cat":"hep-th","submitted_at":"2025-11-03T19:00:04+00:00","verdict":"UNVERDICTED","verdict_confidence":"LOW","novelty_score":6.0,"formal_verification":"none","one_line_summary":"In the double-scaled SYK model with an end-of-the-world brane, the boundary algebra for a single-sided black hole is a type II1 von Neumann factor with non-trivial commutant, preventing full bulk reconstruction and creating a no man's island behind the horizon.","context_count":0,"top_context_role":null,"top_context_polarity":null,"context_text":null},{"citing_arxiv_id":"2508.00060","ref_index":7,"ref_count":1,"confidence":0.98,"is_internal_anchor":true,"paper_title":"Entanglement spreading and emergent locality in Brownian SYK chains","primary_cat":"hep-th","submitted_at":"2025-07-31T18:00:02+00:00","verdict":"UNVERDICTED","verdict_confidence":"LOW","novelty_score":6.0,"formal_verification":"none","one_line_summary":"In a Brownian SYK chain at strong coupling, information from an injected qudit spreads inside a sharp light-cone at the butterfly velocity because the governing dynamics reduce to FKPP domain walls.","context_count":0,"top_context_role":null,"top_context_polarity":null,"context_text":null},{"citing_arxiv_id":"1905.08762","ref_index":46,"ref_count":1,"confidence":0.98,"is_internal_anchor":true,"paper_title":"The entropy of bulk quantum fields and the entanglement wedge of an evaporating black hole","primary_cat":"hep-th","submitted_at":"2019-05-21T17:27:30+00:00","verdict":"CONDITIONAL","verdict_confidence":"MODERATE","novelty_score":7.0,"formal_verification":"none","one_line_summary":"In a 2d evaporating black hole model, large boosts create O(1/G_N) gradients in bulk entropy that move the quantum extremal surface, causing the generalized entropy to follow unitary expectations with information disappearing after a scrambling time and a phase transition at the Page time.","context_count":0,"top_context_role":null,"top_context_polarity":null,"context_text":null}],"limit":50,"offset":0}
