  Spontaneous emergence of organized states in materials driven by
non-equilibrium conditions is of significant fundamental and technological
interest. In many cases, the organized states are complex, hence, with some
well-studied exceptions, their emergence is challenging to predict. In this
article, we show that an unexpectedly diverse collection of dissipative
organized states can emerge in a simple biphasic system consisting of two
liquids under planar confinement. We drive the liquid-liquid interface, which
is held together by capillary forces, out of thermodynamic equilibrium using DC
electrohydrodynamic shearing. As a result, the interface goes through multiple
spontaneous symmetry breakings, leading to various organized non-equilibrium
states. First, at low shearing, the shear-deformed interface becomes unstable
and a 1D quasi-static corrugation pattern emerges. At slightly higher shearing,
we observe topological changes that lead to emergence of active self-propulsive
fluidic filaments and filament networks, as well as ordered bicontinuous
fluidic lattices. Finally, the system transitions into active self-propulsive
droplets, quasi-stationary dissipating polygonal and toroidal droplets, and
ultimately to a chaotic active emulsion of non-coalescing droplets with complex
interactions. Interestingly, this single system captures many features from
continuum non-equilibrium pattern formation and discrete active particles,
which are often considered separate fields of study. The diversity of observed
dissipative organized states is exceptional and points towards many new avenues
in the study of electrohydrodynamics, capillary phenomena, non-equilibrium
pattern formation, and active materials.
