Exact screening constraints for theories of inhomogeneous electrolytes: Generalized Stillinger-Lovett relations and a nonlinear Ward hierarchy.
Exact theories of electrolyte structure must satisfy the nonlocal constraints imposed by electrostatic screening, yet these constraints are most commonly formulated only for homogeneous bulk systems and at the level of two-point correlations. Here, we develop a unified field-theoretic framework that extends them to gen...
