After averaging over fermion couplings, SYK has a collective field description that sometimes has "wormhole" solutions. We study the fate of these wormholes when the couplings are fixed. Working mainly in a simple model, we find that the wormhole saddles persist, but that new saddles also appear elsewhere in the integration space -- "half-wormholes." The wormhole contributions depend only weakly on the specific choice of couplings, while the half-wormhole contributions are strongly sensitive. The half-wormholes are crucial for factorization of decoupled systems with fixed couplings, but they vanish after averaging, leaving the non-factorizing wormhole behind.

  1. Wormholes and the imaginary distance bound

    hep-th 2026-05 unverdicted novelty 7.0 of 10

    Wormhole solutions with imaginary scalars set an Imaginary Distance Bound on analytic continuation of couplings, enforced by stringy effects that coincide with WGC and KSW in special cases.

  2. Black Holes and Random Variables

    hep-th 2026-07 unverdicted novelty 6.0 of 10

    High-energy CFT and black-hole interval counts are conjectured to obey the FHK extreme-value law; the resulting O(1) erratic fluctuations limit semiclassical AdS precision to e^{-S0}.

  3. The Baby Universe is Fine and the CFT Knows It: On Holography for Closed Universes

    hep-th 2025-07 conditional novelty 5.0 of 10

    A closed universe in AdS/CFT is not ruled out by recent SWAP-test arguments; the one-dimensional Hilbert space seen from the CFT is external indistinguishability, and CFT data can reconstruct the closed universe's geometry.

  4. Correlation Functions and Chaotic Behavior of the SYK Chain Model in Pure States

    hep-th 2025-06 conditional novelty 5.0 of 10

    In a chain of SYK quantum dots, two- and four-point correlators computed in individual energy eigenstates closely match thermal averages, indicating fast scrambling despite slow entanglement growth.
