| Popis: | We introduce a new equation we dubbed the modular Dirac equation to see and reconstruct a spin 1/2 particle at the center of a nearly $AdS_2$ spacetime in the entanglement wedge reconstruction paradigm and we study hidden symmetries of this spacetime, too. Various properties of the Dirac modular operator are studied: a generalized Tomita-Takesaki construction, the connection to the Schwarzian derivative of the logarithm of the modular Dirac operator, the link with the an allowable complex metric, the connection to regenesis, we write the corresponding Lagrangian of the modular Dirac equation and we put in perspective some limitations of the current bulk reconstruction in the case of unknown couplings.
