Statistics and Topology of Fluctuating Ribbons
Ee Hou Yong, Farisan Dary, Luca Giomi +1
Ribbons are a class of slender structures whose length, width, and thickness are widely separated from each other. This scale separation gives a ribbon unusual mechanical propertie…
Detecting Lagrangian coherent structures from sparse and noisy trajectory data
Saviz Mowlavi, Mattia Serra, Enrico Maiorino +1
Many complex flows such as those arising from ocean plastics in geophysics or moving cells in biology are characterized by sparse and noisy trajectory datasets. We introduce techni…
Geometric control of topological dynamics in a singing saw
Suraj Shankar, Petur Bryde, L. Mahadevan
The common handsaw can be converted into a bowed musical instrument capable of producing exquisitely sustained notes when its blade is appropriately bent. Acoustic modes localized…
Geometrical dynamics of edge-driven surface growth
C. Nadir Kaplan, L. Mahadevan
Accretion of mineralized thin wall-like structures via localized growth along their edges is observed in a range of physical and biological systems ranging from molluscan and brach…
Active nematic defects and epithelial morphogenesis
Farzan Vafa, L. Mahadevan
Inspired by recent experiments that highlight the role of nematic defects in the morphogenesis of epithelial tissues, we develop a minimal framework to study the dynamics of an act…
Defect-mediated dynamics of coherent structures in active nematics
Mattia Serra, Linnea Lemma, Luca Giomi +2
Active fluids, such as cytoskeletal filaments, bacterial colonies and epithelial cell layers, exhibit distinctive orientational coherence, often characterized by nematic order and…
Combing a double helix
Thomas Bolton Plumb-Reyes, Nicholas Charles, L. Mahadevan
Combing hair involves brushing away the topological tangles in a collective curl. Using a combination of experiment and computation, we study this problem that naturally links topo…
Wallpaper group kirigami
Lucy Liu, Gary P. T. Choi, L. Mahadevan
Kirigami, the art of paper cutting, has become a paradigm for mechanical metamaterials in recent years. The basic building blocks of any kirigami structures are repetitive deployab…
