We use numerical simulations to investigate the hydrodynamic behavior of the interface between nematic (N) and isotropic (I) phases of a confined active liquid crystal. At low activities, a stable interface with constant shape and velocity is observed separating the two phases. For nematics in homeotropic channels, the velocity of the interface at the NI transition increases from zero (i) linearly with the activity for contractile systems and (ii) quadratically for extensile ones.

Director alignment at the nematic–isotropic interface: elastic anisotropy and active anchoring

TLDR
The results of the simulations reveal that the active anchoring dominates except at very low activities, when the interfaces are static, and it is found that the elastic anisotropy does not affect the dynamics but changes the active length that becomes anisotropic.

Propagation of active nematic-isotropic interfaces on substrates.

TLDR
A hydrodynamic multiphase model is used to investigate the propagation of interfaces of active nematics on substrates and finds an activity dependent threshold, above which the turbulent active nematic forms isolated islands that shrink until the system becomes isotropic and below which theActive nematic expands, with a well defined propagating interface.

Lattice-Boltzmann simulation of free nematic-isotropic interfaces

We use a hybrid method of lattice Boltzmann and finite differences to simulate flat and curved interfaces between the nematic and isotropic phases of a liquid crystal described by the Landau-de

From the mitotic spindle up to tissues and biofilms, many biological systems behave as active droplets, which often break symmetry and change shape spontaneously. Here, I show that active nematic

Braiding Dynamics in Active Nematics

In active matter systems, energy consumed at the small scale by individual agents gives rise to emergent flows at large scales. For 2D active nematic microtubule (ANMT) systems, these flows are

TLDR
It is concluded that hydrodynamic and steric interactions enable different modes of surface dynamics, morphology and thus front invasion in swarming Serratia marcescens.

Oscillatory chiral flows in confined active fluids with obstacles

The authors combine experiments and simulations to investigate collective chiral states of a confined polar active fluid with scatterers and show the onset of three dynamic steady states.

Motility of active nematic films driven by "active anchoring".

TLDR
It is demonstrated that directed fluid flow spontaneously emerges in cases where the two anchoring types are opposing, and its results might be relevant for the design of active microfluidic geometries or curvature-guided self-assembly.

Interfacial motion in flexo- and order-electric switching between nematic filled states

TLDR
It is found that order-electric coupling between the fluid and the field provides a means of switching between states where the plateaux between grooves are dry and states where they are wetted by a nematic layer, without affecting the configuration of the nematic within the groove.

Colloidal particles at a nematic-isotropic interface: Effects of confinement

TLDR
These experiments quantify the scenario where particles move along complex trajectories: they are first captured by the interface and then “glide” towards its vertex point, and numerical minimization of the Landau-de Gennes free energy allows for a qualitative description of the interfacial structure and the drag force.

Biphasic, lyotropic, active nematics.

TLDR
Dynamical simulations of a two-dimensional active nematic fluid in coexistence with an isotropic fluid show an effective anchoring develops at the nematic-isotropic interface, and quenching the active lyotropic fluid results in a steady state.

The effect of anchoring on the nematic flow in channels.

Understanding the flow of liquid crystals in microfluidic environments plays an important role in many fields, including device design and microbiology. We perform hybrid lattice-Boltzmann

Intrinsic Free Energy in Active Nematics

Basing our arguments on the theory of active liquid crystals, we demonstrate, both analytically and numerically, that the activity can induce an effective free energy which enhances ordering in

Spontaneous flow states in active nematics: A unified picture

Continuum hydrodynamic models of active liquid crystals have been used to describe dynamic self-organising systems such as bacterial swarms and cytoskeletal gels. A key prediction of such models is

A nonequilibrium force can stabilize 2D active nematics

TLDR
It is shown that nematic suspensions on a substrate can display order at arbitrarily high activity due to a previously unreported, potentially stabilizing active force, which emerges inevitably in theories of active orientable fluids under geometric confinement.

Active nematics

TLDR
The authors review the subfield of active nematics and provide a comparison between theoretical findings and the corresponding experimental realisations and focus primarily on microtubule–kinesin mixtures and the hydrodynamic theories that describe their properties.
