IMAIA: Interactive Maps AI Assistant for Travel Planning and Geo-Spatial Intelligence

Jieren Deng, Zhizhang Hu, Ziyan He +4

Map applications are still largely point-and-click, making it difficult to ask map-centric questions or connect what a camera sees to the surrounding geospatial context with view-c…

Computing with non-orientable defects: nematics, smectics and natural patterns

Chiqun Zhang, Amit Acharya, Alan C. Newell +1

Defects are a ubiquitous feature of ordered media. They have certain universal features, independent of the underlying physical system, reflecting their topological origins. While…

Finite element approximation of the fields of bulk and interfacial line defects

Chiqun Zhang, Amit Acharya, Saurabh Puri

A generalized disclination (g.disclination) theory [AF15] has been recently introduced that goes beyond treating standard translational and rotational Volterra defects in a continu…

Computational modeling of tactoid dynamics in chromonic liquid crystals

Chiqun Zhang, Amit Acharya, Noel J. Walkington +1

Motivated by recent experiments, the isotropic-nematic phase transition in chromonic liquid crystals is studied. As temperature decreases, nematic nuclei nucleate, grow, and coales…

On the relevance of generalized disclinations in defect mechanics

Chiqun Zhang, Amit Acharya

The utility of the notion of generalized disclinations in materials science is discussed within the physical context of modeling interfacial and bulk line defects like defected gra…

A non-traditional view on the modeling of nematic disclination dynamics

Chiqun Zhang, Xiaohan Zhang, Amit Acharya +2

Nonsingular disclination dynamics in a uniaxial nematic liquid crystal is modeled within a mathematical framework where the kinematics is a direct extension of the classical way of…
