Active nematic flows confined in a two-dimensional channel with hybrid alignment at the walls: A unified picture

We study active nematic fluids confined in narrow channels with a conflicting anchoring at the walls. In this configuration flows are sustained even in the zero activity limit. We use a numerical approach to span a wide portion of parameter space and provide a unified picture of this system beyond the limiting regime explored previously, which stresses the key role played by the activity and the flow aligning parameter. We also show that solutions depend on two dimensionless parameters and present examples of biaxial solutions and the parameter values for which they are observed.
