On the free energy within the mean-field approximation
R. Agra, F. van Wijland, E. Trizac
We compare two widespread formulations of the mean-field approximation, based on minimizing an appropriately built mean-field free energy. We use the example of the antiferromagnet…

The interplay between screening properties and colloid anisotropy: towards a reliable pair potential for disc-like charged particles
R. Agra, E. Trizac, L. Bocquet
The electrostatic potential of a highly charged disc (clay platelet) in an electrolyte is investigated in detail. The corresponding non-linear Poisson-Boltzmann (PB) equation is so…
