Bulk-boundary entanglement correspondence and the Ryu-Takayanagi conjecture in an $AdS_2/CFT_1$ setup
For a free scalar plus Majorana field in AdS2, boundary thermofield-double entanglement entropy matches, up to additive constants, the bulk horizon entanglement entropy and the log of a near-boundary geodesic length.
