Active nematic defects in compressible and incompressible flows
Supavit Pokawanvit, Zhitao Chen, Zhihong You +3
We study the dynamics of active nematic films on a substrate driven by active flows with or without the incompressible constraint.Through simulations and theoretical analysis, we s…
Spontaneous tilt of single-clamped thermal elastic sheets
Zhitao Chen, Duanduan Wan, Mark J. Bowick
Very thin elastic sheets, even at zero temperature, exhibit nonlinear elastic response by virtue of their dominant bending modes. Their behavior is even richer at finite temperatur…
The role of fluid flow in the dynamics of active nematic defects
Luiza Angheluta, Zhitao Chen, M. Cristina Marchetti +1
We adapt the Halperin-Mazenko formalism to analyze two-dimensional active nematics coupled to a generic fluid flow. The governing hydrodynamic equations lead to evolution laws for…
