Landau-de Gennes corrections to the Oseen-Frank theory of nematic liquid crystals
Giovanni Di Fratta, Jonathan Robbins, Valeriy Slastikov +1
We study the asymptotic behavior of the minimisers of the Landau-de Gennes model for nematic liquid crystals in a two-dimensional domain in the regime of small elastic constant. At…
Walker solution for Dzyaloshinskii domain wall in ultrathin ferromagnetic films
Valeriy V. Slastikov, Cyrill B. Muratov, Jonathan M. Robbins +1
We analyze the electric current and magnetic field driven domain wall motion in perpendicularly magnetized ultrathin ferromagnetic films in the presence of interfacial Dzyaloshinsk…
Liquid crystal defects in the Landau-de Gennes theory in two dimensions-beyond the one-constant approximation
Georgy Kitavtsev, Jonathan M Robbins, Valeriy Slastikov +1
We consider the two-dimensional Landau-de Gennes energy with several elastic constants, subject to general -radially symmetric boundary conditions. We show that for generic elas…
Dzyaloshinskii-Moriya domain walls in magnetic nanotubes
Arseni Goussev, J. M. Robbins, Valeriy Slastikov +1
We present an analytic study of domain-wall statics and dynamics in ferromagnetic nanotubes with spin-orbit-induced Dzyaloshinskii-Moriya interaction (DMI). Even at the level of st…
Half-integer point defects in the -tensor theory of nematic liquid crystals
G. Di Fratta, JM Robbins, V. Slastikov +1
We investigate prototypical profiles of point defects in two dimensional liquid crystals within the framework of Landau-de Gennes theory. Using boundary conditions characteristic o…
Domain wall motion in ferromagnetic nanotubes: Analytic results
Arseni Goussev, JM Robbins, Valeriy Slastikov
Dynamics of magnetization domain walls (DWs) in thin ferromagnetic nanotubes subject to longitudinal external fields is addressed analytically in the regimes of strong and weak pen…
