Spontaneous chiralization of polar active colloids De Corato, Marco Pagonabarraga Mora, Ignacio Natale, Giovanniantonio Col·loides Quiralitat Partícules (Matèria) Colloids Chirality Particles Polar active particles constitute a wide class of active matter that is able to propel along a preferential direction, given by their polar axis. Here, we demonstrate a generic active mechanism that leads to their spontaneous chiralization through a symmetry-breaking instability. We find that the transition of an active particle from a polar to a chiral symmetry is characterized by the emergence of active rotation and of circular trajectories. The instability is driven by the advection of a solute that interacts differently with the two portions of the particle surface and it occurs through a supercritical pitchfork bifurcation. 2022-04-06T14:15:47Z 2022-04-06T14:15:47Z 2021-06-01 2022-04-06T14:15:47Z info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion 2470-0045 https://hdl.handle.net/2445/184777 719757 eng Reproducció del document publicat a: https://doi.org/10.1103/PhysRevE.104.044607 Physical Review e, 2021, vol. 104, num. 4, p. 044607 https://doi.org/10.1103/PhysRevE.104.044607 info:eu-repo/grantAgreement/EC/H2020/766972/EU//NANOPHLOW info:eu-repo/grantAgreement/EC/H2020/712754/EU//BEST (c) American Physical Society, 2021 info:eu-repo/semantics/openAccess application/pdf application/pdf American Physical Society Articles publicats en revistes (Física de la Matèria Condensada)
