From Knots to Crystals: Machine-Learned Potentials for Self-Assembling Topological Solitons in Liquid Crystals
Arunkumar Bupathy, Darian Hall, Ivan I. Smalyukh +3
Knotted fields in classical and quantum systems have long been recognized for their non-trivial topologies and particle-like behavior, but practical applications have been limited…
Machine learning many-body potentials for charged colloids in primitive 1:1 electrolytes
Thijs ter Rele, Gerardo Campos-Villalobos, René van Roij +1
Effective interactions between charged particles dispersed in an electrolyte are most commonly modeled using the Derjaguin-Landau-Verwey-Overbeek (DLVO) potential, where the ions i…
Shaping boundaries to control and transport topological defects in colloidal nematic liquid crystals
Gerardo Campos-Villalobos, André F. V. Matias, Ethan I. L. Jull +2
Anisotropic rod-like particles form liquid crystalline phases with varying degrees of orientational and translational order. When confined geometrically, these phases can give rise…
Ion Selectivity in Uncharged Tapered Nanoslits through Heterogeneous Water Polarization
Tim Veenstra, Gerardo Campos-Villalobos, Giuliana Giunta +2
We employ molecular dynamics simulations to investigate ion and water transport driven by an electric field through quasi-two-dimensional nanoslits with a tapered geometry. Despite…
Curvature directed anchoring and defect structure of colloidal smectic liquid crystals in confinement
Ethan I. L. Jull, Gerardo Campos-Villalobos, Qianjing Tang +2
Rod-like objects at high packing fractions can form smectic phases, where the rods break rotational and translational symmetry by forming lamellae. Smectic defects thereby include…
