A comprehensive continuum theory of structured liquids

R. Blossey et al.

Summary: We present a comprehensive continuum model that can handle both electrostatic and structural interactions in liquid dielectrics. Using a two-order parameter description based on charge density and polarization, we derive a field-theoretic model that generalizes previous theories. Our theory explicitly includes electrostatic and structural interactions in the bulk of the liquid and allows for polarization charges within a Drude model. We provide a detailed description of the boundary conditions, including the charge regulation mechanism and surface polarization, and analyze an exemplary model case. Future applications for predicting and validating experimental results are outlined.

The effects of an electrolyte solution on screening the Casimir interaction between two symmetric double-layered media

A. Seyedzahedi et al.

Summary: This paper investigates the thermal Casimir force in an electrolyte solution using the scattering approach and Matsubara formalism. The study shows that increasing the concentration of the electrolyte enhances the Casimir force, and the contribution of different layers of media to the Hamaker coefficient is similar. Additionally, the longitudinal modes contribution due to ions in the Hamaker coefficient is weaker when the electrolyte is surrounded by a conductor rather than a dielectric media.
