  We present a table-top realization of a non-equilibrium quantum system
described by a dynamical gauge field propagating on an effectively curved space
and time manifold. The system is formed by neutral atoms interacting with both
a conservative disordered optical field and a dissipative pumping field. In the
presence of a sufficiently dark state, we demonstrate non-equilibrium behavior
reminiscent of the information paradox in black hole physics. At a well-defined
transition point, the analog of gauge-boson mass is seen to vanish, inducing
scale-invariant behavior as a Higgs-like mechanism is removed. The subsequent
scaling behavior can be understood using the holographic principle with a
tunable analog of the Planck length derived from the scaling of disorder. These
effects suggest a range of new phenomena in weakly dissipative quantum systems,
including the presence of analog forms of emergent gravitation.
