In this letter, we provide a theory of AM or active drop (AD) on SS: theory of soft active wetting [see Fig. )]. The theory accounts for various free energies and AS associated with the AM-SS interactions and provide an equilibrium picture of the orientation of active particles inside the drop and the shape of the drop-substrate system. There are three key findings. First, we recover the equilibrium ordered state of the polarization field as described by the Landau de-Gennes theory . Second, the presence of the extensile activity expands and presses down the drop on the substrate, while the contractile activity contracts and pulls up the drop on the substrate. Last, the three-phase contact line (TPCL) undergoes a rotation that depends on the strength of activity. Thus, our findings reveal the trifecta of mechanisms dictating the AD-SS interactions: substrate elasticity resisting shape change, capillary pressure pressing the substrate isotropically, and the directional AS contributing predominantly to the drop curvature. These results challenge the intuition that the bulk active stress stretches or squeezes the substrate directly into a deformed shape; rather, at least for slender drops, AS effectively increase or decrease the contribution of ST in elastocapillary deformation. We start by considering a set-up where the mass of AM rests on a SS. Such a setup mirrors systems such as: elongated cells on soft tissues, drops with microtubules over kinesin motors, lumen formation during embryonic development, or muscle cells contracting soft tissues. From the mathematical standpoint, our system consists of two parts: the first part (ℱ !"! ) that can be expressed in a variational form (i.e., terms that can be represented as gradients of energy functionals), and second, the non-variational terms that alter the equilibrium conditions through activity, pulling the system out of its lowest "energy" state.
