Entangled nematic disclinations using multi-particle collision dynamics
arxiv(2024)
Abstract
Colloids dispersed in nematic liquid crystals form topological composites in
which colloid-associated defects mediate interactions while adhering to
fundamental topological constraints. Better realising the promise of such
materials requires numerical methods that model nematic inclusions in dynamic
and complex scenarios. We employ a mesoscale approach for simulating colloids
as mobile surfaces embedded in a fluctuating nematohydrodynamic medium to study
the kinetics of colloidal entanglement. In addition to reproducing far-field
interactions, topological properties of disclination loops are resolved to
reveal their metastable states and topological transitions during relaxation
towards ground state. The intrinsic hydrodynamic fluctuations distinguish
formerly unexplored far-from-equilibrium disclination states, including
configurations with localised positive winding profiles. The adaptability and
precision of this numerical approach offers promising avenues for studying the
dynamics of colloids and topological defects in designed and out-of-equilibrium
situations.
