Considering (de)protonation as the simplest mechanism of chargeequilibration between the membranes and with the bathing environment, we uncover a symmetry-broken chargestate in the stack with a quasiperiodic effective charge sequence. In the case of a monovalent bathing salt solutionour model predicts complex, inhomogeneous charge equilibria depending on the strength of the (de)protonationreaction, salt concentration, and membrane size. Our results shed light on the basic reorganization mechanismof thylakoid membrane stacks.Show less >
