introduction

The simple exclusion process is a model of a lattice gas with an exclusion principle: a particle can move to a neighboring site, with rate p  for each side, only if this is empty.

exclusion rule which forbids to have more than one particle per site

symmetric exclusion process

particles jumping from left ro right or from right ro left with given probabilityes p and q (p+q=1)

G(x,t) = probability (x(t)=x | x(0) is distrbuted according to g(x) )

 

 

 

KPZ equation

Stochastic growth models in the plane

For simple case, consider a graph of a random height function h.

Consider the rescaling

h^{\epsion}(x,t)=\epsilon h(\frac{x}{\epsilon},\frac{t}{\epsilon})

Then we expect to have

 

 

After some scaling argument, one may use KPZ equation to justify \epsilon^{2/3} as the order og the fluctuations of the above problem. But what is the law of the random \eta ?

Perhaps we can locate an example for which we can find exact formula for h as a result a formula for \eta. So for we have two examples that are "exactly solvable"

These examples are

Hammersley-Aldous-Diaconis (HAD) process and simple exclusion processes.

For the latter a trick known on Bethe ansatz is used to find very explicit formulas for various quantities of interest.
