12 Nov 2015 | Abstract: | Magnetotactic swimmers tend to align along magnetic field lines against
stochastic reorientations. We show that the swimming strategy, e.g. active
Brownian motion versus run-and-tumble dynamics, strongly affects the
orientation statistics. The latter can exhibit a velocity condensation whereby
the alignment probability density diverges. As a consequence, we find that the
swimming strategy affects the nature of the phase transition to collective
motion, indicating that L’evy run-and-tumble walks can outperform active
Brownian processes as strategies to trigger collective behavior. | Source: | arXiv, 1511.3790 | Services: | Forum | Review | PDF | Favorites |
