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…
