Furthermore, we show that the overlap between the condensed layers on two like-charged surfaces leads to a short-range attraction. At high salt concentrations, the condensed layer dissolves, and a reentrant repulsive force appears. Our work provides the first explanation of the resolubilization of charged colloids in agreement with the non-monotonic nature of the effective surface charge.
