Mode-coupling theory of single-file diffusion


Ooshida Takeshi (Tottori University)


Diffusion in a one-dimensional system of repulsive Brownian particles, referred to as single-file diffusion (SFD), is known for its anomalous behavior and has been studied as a simplified model of cage dynamics. Here we report how a Lagrangian version of mode-coupling theory, as opposed to the Eulerian one, allows us to handle the anomalous diffusion and calculate the self part of the so-called Q-based chi_4, taking the nonlinearity of the thermodynamic potential into account.
