Mean-Field Theory for the Three-State Active Lattice Gas Model
Ana L. N. Dias, Ronald Dickman, Tiago Venzel Rosembach
We develop a mean-field description including spatial structure for a simplified version of the three-state active matter model studied by Venzel et al. (Phys. Rev. E 110, 014109 (…

Pattern formation in a coupled driven diffusive system
G. E. Freire Oliveira, R. Dickman, M. O. Lavrentovich +1
We investigate pattern formation in a driven mixture of two repulsive particles by introducing a Field-based Lattice Model (FLM), a hybrid model that combines aspects of the driven…

Three-state active lattice gas: a discrete Vicseklike model with excluded volume
Tiago Venzel Rosembach, Ana Luiza Novaes Dias, Ronald Dickman
We study a discrete-space model of active matter with excluded volume. Particles are restricted to the sites of a triangular lattice, and can assume one of three orientations. Vary…
