We study the thermodynamics of Einstein gravity with vanishing cosmological constant subjected to conformal boundary conditions. Our focus is on comparing the series of subextensive terms to predictions from thermal effective field theory, with which we find agreement for the boundary theory on a spatial sphere, hyperbolic space, and flat space. We calculate the leading Wilson coefficients and observe that the first subextensive correction to the free energy is negative. This violates a conjectured bound on this coefficient in quantum field theory, which we interpret as a signal that gravity does not fully decouple in the putative boundary dual.

  1. Ill-posedness of the Cauchy problem for linearized gravity in a cavity with conformal boundary conditions

    gr-qc 2025-05 accept novelty 7.0 of 10

    Linearized gravity in a cavity with conformal boundary conditions is ill-posed: a sequence of smooth perturbations with vanishing initial data grows without bound at every positive time.

  2. Holographic entanglement entropy with conformal boundary conditions

    hep-th 2026-08 conditional novelty 6.0 of 10

    In AdS3 with conformal boundary conditions, holographic entanglement entropy is still the minimal-surface area over 4G_N, and the dual Liouville plus T Tbar theory gives entropy governed by the effective central charge c_eff.

  3. Holographic heat engines for Schwarzschild black holes

    hep-th 2026-07 accept novelty 6.0 of 10

    Schwarzschild black holes in finite cavities yield fixed-theory reversible heat engines with exact cycle efficiencies that probe quasi-local equations of state.

  4. Diamonds in the Bulk and Large-$N$ Scaling in AdS/CFT

    hep-th 2026-01 conditional novelty 6.0 of 10

    Bulk field algebras of causal diamonds in AdS/CFT require a double-scaling limit, so sub-AdS-radius distances are not described by bulk QFT.

  5. Fluid Boundary Conditions from AdS/BCFT

    hep-th 2025-07 conditional novelty 6.0 of 10

    In AdS/BCFT, the metric boundary condition on the end-of-the-world brane determines the fluid boundary condition: Neumann gives no-penetration plus Neumann conditions on velocity and temperature, and Dirichlet gives no-slip.
