Mean-field theory of inhomogeneous fluids

Tschopp, Salomée M. ; Vuijk, Hidde Derk ; Sharma, Abhinav ; Brader, Joseph M.

In: Physical Review E, 2020, vol. 102, no. 4, p. 042140

The Barker-Henderson perturbation theory is a bedrock of liquid-state physics, providing quantitative predictions for the bulk thermodynamic properties of realistic model systems. However, this successful method has not been exploited for the study of inhomogeneous systems. We develop and implement a first-principles “Barker- Henderson density functional,” thus providing a robust and...

Brownian systems with spatially inhomogeneous activity

Sharma, Abhinav ; Brader, Joseph M.

In: Physical Review E, 2017, vol. 96, no. 3, p. 032604

We generalize the Green-Kubo approach, previously applied to bulk systems of spherically symmetric active particles [J. Chem. Phys. 145, 161101 (2016)], to include spatially inhomogeneous activity. The method is applied to predict the spatial dependence of the average orientation per particle and the density. The average orientation is given by an integral over the self part of the Van Hove...
