Abstract: We consider the question of classicality for the theory that is known to be an effective description of two-dimensional black holes—the Morse quantum mechanics. We calculate the Wigner function and the Fisher information characterizing the classicality/quantumness of single-particle systems and briefly discuss further directions to study.
Keywords: AdS/CFT correspondence, Jackiw–Teitelboim gravity.
