Molecular chirality controls droplet division and helical fiber formation in liquid crystal emulsions
Simon Čopar, Mariana V. M. Rodriguez, Peter Marinko +9
Molecular chirality is a source of broken mirror symmetry, but using it to control mesoscale structures with a tunable length scale remains challenging. Here, we demonstrate that a…
Scallop Theorem for Swimming in Anisotropic Fluids
Mojtaba Rajabi, Enej Caf, Qi Xing Zhang +6
In isotropic fluids like water, micrometer-scale swimmers have evolved swim strokes to translate despite their tiny size. As described by Purcell in his Scallop Theorem, reciprocal…
Nematic liquid crystal flow driven by time-varying active surface anchoring
Seyed Reza Seyednejad, Miha Ravnik
We demonstrate the generation of diverse material flow regimes in nematic liquid cells as driven by time-variable active surface anchoring, including no-net flow, oscillatory flow,…
Chirality, anisotropic viscosity and elastic anisotropy in three-dimensional active nematic turbulence
Nika Kralj, Miha Ravnik, Žiga Kos
Various active materials exhibit strong spatio-temporal variability of their orientational order known as active turbulence, characterised by irregular and chaotic motion of topolo…
Three-Dimensional Spontaneous Flow Transition in a Homeotropic Active Nematic
Vincenzo J. Pratley, Enej Caf, Miha Ravnik +1
We study the three-dimensional spontaneous flow transition of an active nematic in an infinite slab geometry using a combination of numerics and analytics. We show that it is deter…
Controllable shifting, steering, and expanding of light beam based on multi-layer liquid-crystal cells
Urban Mur, Miha Ravnik, David Seč
Shaping and steering of light beams is essential in many modern applications, ranging from optical tweezers, camera lenses, vision correction to 3D displays. However, current reali…
