Variational formulation of active nematic fluids: theory and simulation

New Journal of Physics
The structure and dynamics of important biological quasi-two-dimensional systems, ranging from cytoskeletal gels to tissues, are controlled by nematic order, flow, defects and activity.

Spatiotemporal chaos and defect proliferation in polar-apolar active mixture

New Journal of Physics
Chaotic transitions in inertial fluids typically proceed through a direct energy cascade from large to small scales. In contrast, active systems—composed of self-propelled units—inject energy at microscopic scales and therefore exhibit an inverse cascade,

Control of active nematics

, 2021
Active matter describes systems, such as bacterial suspensions, cellular tissue or cytoskeleton biopolymers, that extract energy from their surroundings at the single-particle level and convert it into mechanical work. The resulting active work can be manifested in the form of self-propulsion and stress generation. The continuous injection of energy or

Three-dimensional spontaneous flow transition in a homeotropic active nematic

Communications Physics
Active nematics are driven, non-equilibrium systems relevant to biological processes including tissue mechanics and morphogenesis, and to active metamaterials in general.
