Spatiotemporal Control of Charge +1 Topological Defects in Polar Active Matter
Birte C. Geerds, Abhinav Singh, Mathieu Dedenon +4
Topological defects are a conspicuous feature of active liquid crystals that have been associated with important morphogenetic transitions in organismal development. Robust develop…
Topological defects lead to energy transfer in active nematics
Daniel J. G. Pearce, Berta Martínez-Prat, Jordi Ignés-Mullol +1
Active nematics are fluids in which the components have nematic symmetry and are driven out of equilibrium due to the microscopic generation of an active stress. When the active st…
Topological defects in multi-layered swarming bacteria
Victor Yashunsky, Daniel J. G. Pearce, Gil Ariel +1
Topological defects, which are singular points in a director field, play a major role in shaping active systems. Here, we experimentally study topological defects and the flow patt…
Passive defect driven morphogenesis in nematic membranes
D. J. G. Pearce, C. Thibault, Q. Chaboche +1
Topological defects are ubiquitous on surfaces with orientational order fields. Here, we study equilibrium states generated by the feedback between geometry and nematic order on fl…
