Boundaries, inclusions and disorder in active matter
Summary
I. Pressure in equilibrium and active matter: Pressure dependence on boundary properties
II. Boundary asymmetry and curvature: Ratchet forces and line tension
III. Inclusions: The long reach of inclusions in disturbing active fluids
IV. Disorder: Long-range correlations and persistent currents
V. Phase separation: Destruction of bulk phase separation by disorder
VI. Boundary disorder: Boundary disorder disrupts bulk order
