Wetting Transition of Active Brownian Particles on a Thin Membrane Physical Review Letters (IF9.161), Pub Date : 2021-12-01, DOI: 10.1103/physrevlett.127.238002 Francesco Turci, Nigel B. Wilding
We study nonequilibrium analogues of surface phase transitions in a minimal model of active particles in contact with a purely repulsive potential barrier that mimics a thin porous membrane. Under conditions of bulk motility-induced phase separation, the interaction strength of the barrier controls the affinity of the dense phase for the barrier region. We uncover clear signatures of a wetting phase transition as is varied. In common with its equilibrium counterpart, the character of this transition depends on the system dimensionality: a continuous transition with large density fluctuations and gas bubbles is uncovered in 2D while 3D systems exhibit a sharp transition absent of large correlations.
