Numerical analysis for constrained and unconstrained Q-tensor energies for liquid crystals

Heiko Gimperlein, Ruma R. Maity

This paper introduces a comprehensive finite element approximation framework for three-dimensional Landau-de Gennes -tensor energies for nematic liquid crystals, with a particul…

Bayesian Parameter Identification in the Landau-de Gennes Theory for Nematic Liquid Crystals

Heiko Gimperlein, Ruma R. Maity, Apala Majumdar +1

This manuscript establishes a pathway to reconstruct material parameters from measurements within the Landau-de Gennes model for nematic liquid crystals. We present a Bayesian appr…

Parameter dependent finite element analysis for ferronematics solutions

Ruma Rani Maity, Apala Majumdar, Neela Nataraj

This paper focuses on the analysis of a free energy functional, that models a dilute suspension of magnetic nanoparticles in a two-dimensional nematic well. The {\it first part} of…

Error analysis of Nitsche's and discontinuous Galerkin methods of a reduced Landau-de Gennes problem

Ruma Rani Maity, Apala Majumdar, Neela Nataraj

We study a system of semi-linear elliptic partial differential equations with a lower order cubic nonlinear term, and inhomogeneous Dirichlet boundary conditions, relevant for two-…

Discontinuous Galerkin Finite Element Methods for the Landau-de Gennes Minimization Problem of Liquid Crystals

Ruma Rani Maity, Apala Majumdar, Neela Nataraj

We consider a system of second order non-linear elliptic partial differential equations that models the equilibrium configurations of a two dimensional planar bistable nematic liqu…
