Diffusion with center of mass conservation
ORAL
Abstract
In normal diffusion, particles move randomly while conserving their total number. What would happen when additional constraints, such as the conservation of the center of mass, are applied? In this talk, I will show that the dynamic exponent of diffusion with center of mass conservation in d-dimension changes to z = d+4, and that the equilibrium distribution is exponentially localized in the presence of a hard wall.
