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 AB, AC, AD, BC, BD, and CD. 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 PSfor 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.
