Ionically charged topological defects in nematic fluids
Jeffrey C. Everts, Miha Ravnik
Charge profiles in liquid electrolytes are of crucial importance for applications, such as supercapacitors, fuel cells, batteries, or the self-assembly of particles in colloidal or…
Topological liquid crystal superstructures as structured light lasers
Miha Papič, Urban Mur, Miha Ravnik +2
Liquid crystals (LCs) form an extremely rich range of self-assembled topological structures with artificially or naturally created topological defects. Some of the main application…
Anisotropic electrostatic screening of charged colloids in nematic solvents
Jeffrey C. Everts, Bohdan Senyuk, Haridas Mundoor +2
The physical behaviour of anisotropic charged colloids is determined by their material dielectric anisotropy, affecting colloidal self-assembly, biological function and even out-of…
Topological-defect-induced surface charge heterogeneities in nematic electrolytes
Miha Ravnik, Jeffrey C. Everts
We show that topological defects in an ion-doped nematic liquid crystal can be used to manipulate the surface charge distribution on chemically homogeneous, charge-regulating exter…
Charge-, salt- and flexoelectricity-driven anchoring effects in nematics
Jeffrey C. Everts, Miha Ravnik
We investigate the effects of electric double layers and flexoelectricity on the surface anchoring in general nematic fluids. Within a simplified model, we demonstrate for a nemati…
Discharging dynamics of topological batteries
Vishal P. Patil, Žiga Kos, Miha Ravnik +1
Topological constraints have long been known to provide efficient mechanisms for localizing and storing energy across a range of length scales, from knots in DNA to turbulent plasm…
