The reduced density matrix of a given subsystem, denoted by $\rho_A$, contains the information on subregion duality in holographic theory. We may extract using spectrum (eigenvalue) matrix, called entanglement this paper. evaluate eigenstates, one-point and two-point correlation functions microcanonical ensemble state $\rho_{A,m}$ associated with an eigenvalue $\lambda$ for some examples, inclu...
