The Multi-trace Eigenstate Thermalization Hypothesis
Ahmed I. Abdalla, Gabriele Di Ubaldo, Elisa Tabor
We introduce a multi-trace eigenstate thermalization hypothesis, an extension of ETH that governs connected correlations of operator matrix elements with arbitrary index structures…

When the gravity path integral describes a statistical average
Gabriele Di Ubaldo, Luca V. Iliesiu, Henry W. Lin +1
We find the necessary and sufficient conditions for the gravitational path integral (GPI) to admit an interpretation in terms of (i) an inner product in the Hilbert space of open/c…

Ensemble averaging in JT gravity from entanglement in Matrix Quantum Mechanics
Gabriele Di Ubaldo, Giuseppe Policastro
We consider the generalization of a matrix integral with arbitrary spectral curve to a 0+1D theory of matrix quantum mechanics (MQM). Using recent techniques for 1D quantu…
