Equal-charge projection of the index: exact large- formula and finite-rank coefficients
Miguel Tierz
The equal-charge branch of supersymmetric rotating AdS black holes has . The corresponding microcanonical sector of the superconformal index is obt…
Exact Schwarzian Metric Factor and Holographic Wilson-Loop Screening
Miguel Tierz
We evaluate exactly the radial metric factor generated by Schwarzian averaging in the AdS throat of an extremal Reissner--Nordström AdS black brane. The result is…
BPS spectra of matrix models for odd
Miguel Tierz
We study the BPS cohomology and Hamiltonian of a model built from an matrix of complex fermions, with supercharge for odd . Numerical cal…
Entanglement in the open XX chain: Rényi oscillations, hard-edge crossover, and symmetry resolution
Miguel Tierz
We derive closed-form asymptotic formulas for the Rényi entanglement entropies of the open XX spin- chain by mapping the underlying determinant of the boundary correlation ma…
Finite Gauss-Sum Modular Kernels: Scalar Gap and a Pure AdS Gravity No-Go Theorem
Miguel Tierz
We obtain closed-form expressions for the modular kernels of non-rational Virasoro CFTs and use them to construct fully analytic modular-bootstrap functionals. At rational…
Integrable Contour Kernels in Discrete Ensembles, Universality and Kuznetsov Multipliers
Miguel Tierz
We obtain explicit double-contour representations for the correlation kernels of the discrete orthogonal () and symplectic () random matrix ensembles with Meixner, Char…
