The control of nonlinear processes and possible transitions to chaos in systems of interacting particles is a fundamental physical problem. We propose a nonuniform solid-state plasma system, produced by the optical injection of current in two-dimensional semiconductor structures, where this control can be achieved. Due to an injected current, the system symmetry is initially broken. The subsequent nonequilibrium dynamics is governed by the spatially varying long-range Coulomb forces and electron-hole collisions. As a result, inhomogeneities in the charge and velocity distributions should develop rapidly and lead to previously unexpected experimental consequences. We suggest that the system eventually evolves into a behavior similar to chaos.
