We study the spectrum of permutation orbifolds of 2d CFTs. We find examples where the light spectrum grows faster than Hagedorn, which is different from known cases such as symmetric orbifolds. We also describe how to compute their partition functions using a generalization of Hecke operators.

  1. Symmetric Product Orbifold Universality and the Mirage of an Emergent Spacetime

    hep-th 2025-02 conditional novelty 7.0 of 10

    Symmetric product orbifolds have large-N thermal correlators identical to BTZ, undercutting the claim that a type III1 von Neumann algebra implies a sharp emergent horizon.

  2. Emergent Closed Universes in Symmetric Orbifold CFTs

    hep-th 2026-06 unverdicted novelty 6.0 of 10

    Large N symmetric orbifold CFTs decompose into superselection sectors that behave as closed universes, with each physical sector becoming one-dimensional after gauging, matching gravitational expectations.
