Coupling topological defect phase to extrinsic curvature in nematic shells
Daniel J. G. Pearce
In two dimensional nematics, topological defects are point like singularities with both a charge and a phase. We study topological defects within curved nematic textures on the sur…
Self-assembly dynamics of reconfigurable colloidal molecules
Indrani Chakraborty, Daniel J. G. Pearce, Ruben W. Verweij +3
Colloidal molecules are designed to mimic their molecular analogues through their anisotropic shape and interactions. However, current experimental realizations are missing the str…
Properties of twisted topological defects in 2D nematic liquid crystals
Daniel J. G. Pearce, Karsten Kruse
Topological defects are one of the most conspicuous features of liquid crystals. In two dimensional nematics, they have been shown to behave effectively as particles with both, cha…
Chiral edge currents in confined fibrosarcoma cells
V. Yashunsky, D. J. G. Pearce, C. Blanch-Mercader +3
During metastatic dissemination, streams of cells collectively migrate through a network of narrow channels within the extracellular matrix, before entering into the blood stream.…
Confinement-induced self-organization in growing bacterial colonies
Zhihong You, Daniel J. G. Pearce, Luca Giomi
We investigate the emergence of global alignment in colonies of dividing rod-shaped cells under confinement. Using molecular dynamics simulations and continuous modeling, we demons…
Mono-to-multilayer transition in growing bacterial colonies
Zhihong You, Daniel J. G. Pearce, Anupam Sengupta +1
The transition from monolayers to multilayered structures in bacterial colonies is a fundamental step in biofilm development. Observed across different morphotypes and species, thi…
