text: Like-charge attraction, driven by ionic correlations, challenges our understanding
of electrostatics both in soft and hard matter. For two charged planar surfaces
confining counterions and water, we prove that, even at relatively low correlation
strength, the relevant physics is the ground-state one, oblivious of fluctuations.
Based on this, we derive a simple and accurate interaction pressure that fulfills
known exact requirements and can be used as an effective potential. We test this
equation against implicit-solvent Monte Carlo simulations and against explicit-solvent
simulations of cement and several types of clays. We argue that water destructuring
under nanometric confinement drastically reduces dielectric screening, enhancing
ionic correlations. Our equation of state at reduced permittivity therefore explains
the exotic attractive regime reported for these materials, even in the absence
of multivalent counterions.
