Abstract:: This thesis is devoted to exploring the connection between thermofield dynamics and microscopic descriptions of black holes in large N matrix quantum mechanics. We uncover a dynamical symmetry, based on which the construction of thermofield double states is given. For this we adopt a master field constrained optimization scheme to systematically evaluate thermal correlations and spectra at large N. We establish a mapping between conformal field theory and the dual gravity of BTZ black hole. We also investigate alternative approaches to bulk reconstruction and subregion duality, employing the Tomita-Takesaki theory and twisted Ishibashi states.
