Emergent dimer-model topological order and quasi-particle excitations in liquid crystals: combinatorial vortex lattices
Cuiling Meng, Jin-Sheng Wu, Žiga Kos +3
Liquid crystals have proven to provide a versatile experimental and theoretical platform for studying topological objects such as vortices, skyrmions, and hopfions. In parallel, in…
Many-defect solutions in planar nematics: interactions, spiral textures and boundary conditions
Simon Čopar, Žiga Kos
From incompressible flows to electrostatics, harmonic functions can provide solutions to many two-dimensional problems and, similarly, the director field of a planar nematic can be…
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…
Symmetrically pulsating bubbles swim in an anisotropic fluid by nematodynamics
Sung-Jo Kim, Žiga Kos, Eujin Um +1
Swimming in low-Reynolds-number fluids requires the breaking of time-reversal symmetry and centrosymmetry. Microswimmers, often with asymmetric shapes, exhibit nonreciprocal motion…
Defect Line Coarsening and Refinement in Active Nematics
Nika Kralj, Miha Ravnik, Žiga Kos
Active matter is naturally out of equilibrium which results in the emergence of diverse dynamic steady states, including the omnipresent chaotic state known as the active turbulenc…
Nematic colloidal micro-robots as physically intelligent systems
Tianyi Yao, Žiga Kos, Yimin Luo +4
Physically intelligent micro-robotic systems exploit information embedded in micro-robots, their colloidal cargo, and their milieu to interact, assemble and form functional structu…
Harmonic flow field representations of quantum bits and gates
Vishal P. Patil, Žiga Kos, Jörn Dunkel
We describe a general procedure for mapping arbitrary -qubit states to two-dimensional (2D) vector fields. The mappings use complex rational function representations of individu…
Topological defect-propelled swimming of nematic colloids
Tianyi Yao, Žiga Kos, Yimin Luo +3
Non-equilibrium dynamics of topological defects can be used as a fundamental propulsion mechanism in microscopic active matter. Here, we demonstrate swimming of topological defect-…
Nematic bits and universal logic gates
Žiga Kos, Jörn Dunkel
Liquid crystals (LCs) can host robust topological defect structures that essentially determine their optical and elastic properties. Although recent experimental progress enables p…
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…
Sculpting stable structures in pure liquids
Tadej Emeršič, Rui Zhang, Žiga Kos +4
Pure liquids in thermodynamic equilibrium are structurally homogeneous. In liquid crystals, flow and light pulses are used to create reconfigurable domains with polar order. Moreov…
Microfluidic control over topological states in channel-confined nematic flows
Simon Čopar, Žiga Kos, Tadej Emeršič +1
Compared to isotropic liquids, orientational order of nematic liquid crystals makes their rheological properties more involved, and thus requires fine control of the flow parameter…
Spectral energy analysis of bulk three-dimensional active nematic turbulence
Žiga Krajnik, Žiga Kos, Miha Ravnik
We perform energy spectrum analysis of the active turbulence in 3D bulk active nematic using continuum numerical modelling. Specifically, we calculate the spectra of two main energ…
Three-Dimensional Active Defect Loops
Jack Binysh, Žiga Kos, Simon Čopar +2
We describe the flows and morphological dynamics of topological defect lines and loops in three-dimensional active nematics and show, using theory and numerical modelling, that the…
Topology of three-dimensional active nematic turbulence confined to droplets
Simon Čopar, Jure Aplinc, Žiga Kos +2
Active nematics contain topological defects which under sufficient activity move, create and annihilate in a chaotic quasi-steady state, called active turbulence. However, understa…
Cross-talk between topological defects in different fields revealed by nematic microfluidics
Luca Giomi, Žiga Kos, Miha Ravnik +1
Topological defects are singularities in material fields that play a vital role across a range of systems: from cosmic microwave background polarization to superconductors, and bio…
