The role of topological defects in the two-stage melting and elastic behavior of active Brownian particles
Siddharth Paliwal, Marjolein Dijkstra
We find that crystalline states of repulsive active Brownian particles at high activity melt into a hexatic state but this transition is not driven by an unbinding of bound disloca…
Ratchet-induced variations in bulk states of an active ideal gas
Jeroen Rodenburg, Siddharth Paliwal, Marjolein de Jager +3
We study the distribution of active, noninteracting particles over two bulk states separated by a ratchet potential. By solving the steady-state Smoluchowski equations in a flux-fr…
Non-Equilibrium Surface Tension of the Vapour-Liquid Interface of Active Lennard-Jones Particles
Siddharth Paliwal, Vasileios Prymidis, Laura Filion +1
We study a three-dimensional system of self-propelled Brownian particles interacting via the Lennard-Jones potential. Using Brownian Dynamics simulations in an elongated simulation…
