Inter-layer interaction. State transitions of the well-polarized cell and the corresponding response functions of the observed cell. Six state transitions are presented, namely A$\to$B, A$\to$C, A$\to$D, B$\to$C, B$\to$D, and C$\to$D. For all cases throughout a series of sequential steps, a transition from the initial state to neutral and then from the neutral state to the final state is applied to the well-polarized cell, and the response of the observed cell is computed. For each transition, there are four graphs depicting the density correlation function _{P S}for states A, B, C, and D. The lighter curve (blue) is for the well-polarized cell, and the darker curve (orange) is the response of the observed cell. Notice that states A, B, C, and D of the well-polarized cell induce states B, A, D, and C in the observed cell, respectively.
