Compatible director fields in
Luiz C. B. da Silva, Tal Bar, Efi Efrati
The geometry and interactions between the constituents of a liquid crystal, which are responsible for inducing the partial order in the fluid, may locally favor an attempted phase…
Bridging cumulative and non-cumulative geometric frustration response via a frustrated -state spin system
Snir Meiri, Efi Efrati
The resolution of geometric frustration in systems with continuous degrees of freedom often involves a cooperative inhomogeneous response and super-extensive energy scaling. In con…
Cumulative geometric frustration and superextensive energy scaling in a nonlinear classical XY-spin model
Snir Meiri, Efi Efrati
Geometric frustration results from a discrepancy between the locally favored arrangement of the constituents of a system and the geometry of the embedding space. Geometric frustrat…
Moving frames and compatibility conditions for three-dimensional director fields
Luiz C. B. da Silva, Efi Efrati
The geometry and topology of the region in which a director field is embedded impose limitations on the kind of supported orientational order. These limitations manifest as compati…
Cumulative geometric frustration in physical assemblies
Snir Meiri, Efi Efrati
Geometric frustration arises whenever the constituents of a physical assembly locally favor an arrangement that cannot be realized globally. Recently, such frustrated assemblies we…
Curved geometries from planar director fields - Solving the two-dimensional inverse problem
Itay Griniasty, Hillel Aharoni, Efi Efrati
Thin nematic elastomers, composite hydrogels and plant tissues are among many systems that display uniform anisotropic deformation upon external actuation. In these materials, the…
