abstract

We show that the spectrum of the SYK model can be interpreted as that of a 3D scalar coupled to gravity. The scalar has a mass which is at the Breitenholer-Freedman bound of AdS$_2$, and subject to a delta function potential at the center of the interval along the third direction. This, through Kaluza-Klein procedure on AdS$_2 \times (S^1)/Z_2$, generates the spectrum reproducing the bi-local propagator at strong coupling. Furthermore, the leading $1/J$ correction calculated in this picture reproduces the known correction to the poles of the SYK propagator, providing credence to a conjecture that the bulk dual of this model can be interpreted as a three dimensional theory.

  1. Melonic Dominance in Subchromatic Sextic Tensor Models

    hep-th 2019-08 conditional novelty 7.0 of 10

    Sextic tensor models with O(N)^r symmetry and r<5 have exactly three maximally-single-trace interaction vertices, and each yields a large N limit dominated by (generalized) melonic diagrams.

  2. Sine-dilaton gravity vs double-scaled SYK: exploring one-loop quantum corrections

    hep-th 2024-11 conditional novelty 6.0 of 10

    The one-loop gravitational path integral of sine-dilaton gravity reproduces the one-loop corrections of double-scaled SYK for the free energy (up to an ordering ambiguity) and exactly for the matter two-point function.

  3. Schwarzian functional integrals calculus

    hep-th 2019-08 conditional novelty 6.0 of 10

    Schwarzian functional integrals over Diff^1_+(S^1)/SL(2,R) are reduced to ordinary integrals, giving two- and four-point correlators that do not factorize into two-point products.

    hep-th 2019-08 conditional novelty 6.0 of 10

    For JT gravity with conformal matter, the generalized entropy defined from the horizon dilaton plus matter entanglement is monotonic along the event horizon and along future Q-screens under the null energy condition, ...
