N=4 Super Yang-Mills theory supplies us with a non-Abelian 4D gauge theory with a meaningful perturbation expansion, both in the UV and in the IR. We calculate the free energy on a 3-sphere and observe a deconfinement transition for large N at zero coupling. The same thermodynamic behaviour is found for a wide class of toy models, possibly also including the case of non-zero coupling. Below the transition we also find Hagedorn behaviour, which is identified with fluctuations signalling the approach to the deconfined phase. The Hagedorn and the deconfinement temperatures are identical. Application of the AdS/CFT correspondence gives a connection between string Hagedorn behaviour and black holes.

  1. Overcrowding and the Finite-$N$ Hilbert Space

    hep-th 2026-07 accept novelty 7.0

    For d Hermitian N x N matrices, any all-single-trace choice of primary coordinates must miss a trace direction by degree 2 log_d N + log_d log_d N + O(1), parametrically below the first trace identity.

  2. Fermionic trace relations and supersymmetric indices at finite $N$

    hep-th 2026-05 unverdicted novelty 7.0

    The supersymmetric index in a one-fermion matrix model for N=4 SYM is independent of N due to exact cancellations between bosonic and fermionic trace relations.

  3. Critical dimensions and small cycle dominance from all-orders asymptotics of $d$-matrix theory

    hep-th 2026-03 conditional novelty 7.0

    The weighted partition numbers of d-matrix theory admit an all-orders asymptotic expansion that switches from divergent to convergent at d=13 (bosonic) or 7 (fermionic).

  4. The CFT Distance Conjecture and Tensionless String Limits in $\mathcal N=2$ Quiver Gauge Theories

    hep-th 2026-01 unverdicted novelty 7.0

    In N=2 SU quiver theories the large-N Hagedorn temperature depends only on quiver length for linear cases and equals that of N=4 SYM for holographic quivers, with a universal lower bound of 1/sqrt(2) on the exponentia...

  5. Negative heat capacities in spherically symmetric sectors of $d$-matrix quantum mechanics

    hep-th 2026-06 unverdicted novelty 6.0

    SO(d) and O(d) invariant sectors of d-matrix QM show negative microcanonical heat capacity that becomes positive at k_crit ~ N^2/4, forming a caloric fold similar to AdS black holes.

  6. Negative heat capacities in spherically symmetric sectors of $d$-matrix quantum mechanics

    hep-th 2026-06 conditional novelty 6.0

    In SO(d)- and O(d)-invariant sectors of the U(N) d-matrix harmonic oscillator, microcanonical heat capacity is negative at low energy and turns positive at kcrit ~ N^2/4, producing a caloric fold analogous to AdS black holes.

  7. Gravitational index, black hole saddle degeneracy, and one-form symmetry

    hep-th 2026-06 conditional novelty 6.0

    The |G|-fold degeneracy of supersymmetric AdS5 black hole index saddles is fixed by the flux-quantized BF coupling of the bulk one-form symmetry and persists unmodified in the decompactified black-brane limit.

  8. Instanton condensation and a new phase of BPS black holes

    hep-th 2026-03 unverdicted novelty 6.0

    Instanton condensation in the matrix model for the BPS index reveals a new instability and dominant phase for small black holes, connected to partial deconfinement.

  9. Explorations of Universality in the Entropy and Hawking Radiation of Non-Extremal Kerr AdS$_4$ Black Holes

    hep-th 2025-08 unverdicted novelty 6.0

    Multiple microscopic methods confirm universality of AdS4 black hole entropy for non-extremal cases at high temperatures and show Hawking radiation rate proportional to horizon area.

  10. Wilson Towers as Local Bulk Fields

    hep-th 2026-07 conditional novelty 5.0

    A multi-winding Wilson loop in thermal AdS3 is re-expressed as a sum over single-winding Wilson loops, one per multi-trace primary, so a free bulk field becomes a tower of Wilson lines.

  11. Gravitational index, black hole saddle degeneracy, and one-form symmetry

    One-form symmetry induces degeneracy in black hole saddles for the superconformal index, realized gravitationally with spontaneous breaking illustrated via black hole to black brane transition in the small chemical po...
