| Research Abstract |
We have investigated exact time evolution properties of the stochastic models which describe nonequilibrium systems especially the asymmetric simple exclusion process, which is a many-body random walk model and the Kardar-Parisi-Zhnag equation, a basic equation for surface growth phenomena. In some important initial conditions, we have obtained exact expressions for the probability distribution functions of some important physical quantities such as current, height etc.
