Query: Reconstruction of the polarization distribution of the Rice-Mele model   We calculate the gauge invariant cumulants (and moments) associated with the
Zak phase in the Rice-Mele model. We reconstruct the underlying probability
distribution by maximizing the information entropy and applying the moments as
constraints. When the Wannier functions are localized within one unit cell, the
probability distribution so obtained corresponds to that of the Wannier
function. We show that in the fully dimerized limit the magnitude of the
moments are all equal. In this limit, if the on-site interaction is decreased
towards zero, the distribution shifts towards the midpoint of the unit cell,
but the overall shape of the distribution remains the same. Away from this
limit, if alternate hoppings are finite, and the on-site interaction is
decreased, the distribution also shifts towards the midpoint of the unit cell,
but it does this by changing shape, by becoming asymmetric around the maximum,
as well as by shifting. We also follow the probability distribution of the
polarization in cycles around the topologically non-trivial point of the model.
The distribution moves across to the next unit cell, its shape distorting
considerably in the process. If the radius of the cycle is large, the shift of
the distribution is accompanied by large variations in the maximum.
