We demonstrate that both microwave resonant absorptions and multiple-branch structures in the I-V characterisitcs observed in intrinsic Josephson junctions (IJJ's) are caused by dynamical breaking of charge neutrality (DBCN) inside the atomic-scale superconducting layer. The Lagranginan for the time-dependent Lawrence-Doniach model incorporating the effect of the DBCN is proposed, and the longitudinal collective Josephson plasma mode is proved to exist based on the Lagrangian. On the other hands, the branching behaviors in the I-V curves are almost completely reproduced by careful numerical simulations for the model equation derived from the Lagragian.
