Ordered Phases in Coupled Driven Systems

Mustansir Barma (TIFR Centre for Interdisciplinary Sciences, Tata Institute of Fundamental Research, Hyderabad, India)

Instabilities in the hydrodynamic equations for coupled, driven diffusive systems can herald macroscopic phase separation. We study the resulting ordered phases in a lattice model of light and heavy particles sliding under gravity on a fluctuating surface in 1D or 2D.   We find strong phase separation with fluctuationless phases for particles, but a different organization for the landscape, leading to intricate steady state dynamics of interfaces between phases.
