Flexoelectric switching in cholesteric blue phases
A. Tiribocchi, M. E. Cates, G. Gonnella +2
We present computer simulations of the response of a flexoelectric blue phase network, either in bulk or under confinement, to an applied field. We find a transition in the bulk be…
Bulk rheology and microrheology of active fluids
G. Foffano, J. S. Lintuvuori, A. N. Morozov +3
We simulate macroscopic shear experiments in active nematics and compare them with microrheology simulations where a spherical probe particle is dragged through an active fluid. In…
Switching dynamics in cholesteric blue phases
A. Tiribocchi, G. Gonnella, D. Marenduzzo +1
Blue phases are networks of disclination lines, which occur in cholesteric liquid crystals near the transition to the isotropic phase. They have recently been used for the new gene…
Colloids in liquid crystals: a lattice Boltzmann study
J. S. Lintuvuori, D. Marenduzzo, K. Stratford +1
We propose a hybrid lattice Boltzmann algorithm to simulate the hydrodynamics of colloidal particles inside a liquid crystalline host. To validate our algorithm, we study the stati…
Switching and defect dynamics in multistable liquid crystal devices
A. Tiribocchi, G. Gonnella, D. Marenduzzo +1
We investigate the switching dynamics of multistable nematic liquid crystal devices. In particular we identify a remarkably simple 2-dimensional (2D) device which exploits hybrid a…
Colloids in Cholesterics: Size-Dependent Defects and Non-Stokesian Microrheology
J. S. Lintuvuori, K. Stratford, M. E. Cates +1
We simulate a colloidal particle (radius R) in a cholesteric liquid crystal (pitch p) with tangential order parameter alignment at the particle surface. The local defect structure…
