Timelike Entanglement Signatures of Ergodicity and Spectral Chaos
Rathindra Nath Das, Arnab Kundu, Nemai Chandra Sarkar
We investigate timelike entanglement measures derived from the spacetime density kernel in the Rosenzweig-Porter model and show that they sharply diagnose both eigenvector ergodici…
