Topological delocalisation of confined 3D active nematics
Louise C. Head, Pasquale Digregorio, Davide Marenduzzo +3
Defect lines in 3D active nematic systems are intriguing topological singularities whose out-of-equilibrium dynamics remain elusive in confined settings. Here, we numerically study…
Clifford algebras and liquid crystalline fermions
N. Johnson, L. C. Head, O. D. Lavrentovich +6
We show that Clifford algebras provide a natural language to describe the physics of liquid crystal defects in 3D. This framework shows that most of these defects have fermionic na…
Entangled nematic disclinations using multi-particle collision dynamics
Louise C. Head, Yair A. G. Fosado, Davide Marenduzzo +1
Colloids dispersed in nematic liquid crystals form topological composites in which colloid-associated defects mediate interactions while adhering to fundamental topological constra…
Lock-Key Microfluidics: Simulating Nematic Colloid Advection along Wavy-Walled Channels
Karolina Wamsler, Louise C. Head, Tyler N. Shendruk
Liquid crystalline media mediate interactions between suspended particles and confining geometries, which not only has potential to guide patterning and bottom-up colloidal assembl…
3D active nematic disclinations behave as Majorana quasiparticles
Louise C. Head, Giuseppe Negro, Livio N. Carenza +7
Quasiparticles are low-energy excitations with important roles in condensed matter physics. An intriguing example is provided by Majorana fermions, quasiparticles which are identic…
Controlling flow patterns and topology in active emulsions
Giuseppe Negro, Louise C. Head, Livio N. Carenza +4
Active emulsions and liquid crystalline shells are intriguing and experimentally realisable types of topological matter. Here we numerically study the morphology and spatiotemporal…
Spontaneous Self-Constraint in Active Nematic Flows
Louise C. Head, Claire Dore, Ryan Keogh +5
Active processes drive and guide biological dynamics across scales -- from subcellular cytoskeletal remodelling, through tissue development in embryogenesis, to population-level ba…
