Temperature of an active nematic [PDF]
Physical Review ResearchWe employ a hydrodynamic framework for active matter coupled to an environment to study the local temperature of an active nematic, assuming proximity to thermal equilibrium.

Active Fréedericksz Transition in Active Nematic Droplets
Physical Review XActive nematic liquid crystals have the remarkable ability to spontaneously deform and flow in the absence of any external driving force. While living materials with orientational order, such as the mitotic spindle, can self-assemble in quiescent active ...

Nematic order condensation and topological defects in inertial active nematics
Physical Review E, 2022 Living materials at different length scales manifest active nematic features such as orientational order, nematic topological defects, and active nematic turbulence. Using numerical simulations we investigate the impact of fluid inertia on the collective pattern formation in active nematics.

Active boundary layers in confined active nematics
Nature Communications, 2022 The boundary of conventional liquid crystals is known to anchor the orientational field of the passive materials under equilibrium conditions. Here, the authors show an active nematic to develop active boundary layers that topologically polarize the ...

Spontaneous flows and quantum analogies in heterogeneous active nematic films [PDF]
Communications PhysicsIncorporating the inherent heterogeneity of living systems into models of active nematics is essential to provide a more realistic description of biological processes such as bacterial growth, cell dynamics and tissue development.

Geometry and Topology of Turbulence in Active Nematics [PDF]
Physical Review X, 2015 The problem of low Reynolds number turbulence in active nematic fluids is theoretically addressed. Using numerical simulations, I demonstrate that an incompressible turbulent flow, in two-dimensional active nematics, consists of an ensemble of vortices ...

Casimir stresses in active nematic films [PDF]
New Journal of Physics, 2019 We calculate the Casimir stresses in a thin layer of active fluid with nematic order. By using a stochastic hydrodynamic approach for an active fluid layer of finite thickness L , we generalize the Casimir stress for nematic liquid crystals in thermal ...

Proc Natl Acad Sci U S AMicrofluidics involves the manipulation of flows at the microscale, typically requiring external power sources to generate pressure gradients. Alternatively, harnessing flows from active fluids, which are usually chaotic, has been proposed as a paradigm for the development of micromachines.
