introduction

example of a non-equilibrium model in statistical mechanics
Gibbs-Boltzmann formation is not valid
exclusion rule forbids to have more than one particle per site
The simple exclusion process is a model of a lattice gas with an exclusion principle
diffusion
introduced in 1960's in biology for RNA
analysed in 1990's

formulation

a particle can move to a neighboring site, with probability p to right and probability q to left, only if this is empty.
special cases
- symmetric exclusion process \(p=q=1/2\)
- asymmetric simple exclusion process (ASEP) \(p\neq q\)
- totally asymmetric exclusion process (TASEP) \(p=1,q=0\)
for example, \(\delta=\gamma=q=0\) model for traffic flow
particles jumping from left ro right or from right ro left with given probabilities \(p\) and \(q\) (\(p+q=1\))

dynamical rules

\(P(C,t)\) be the probability for configuration \(C\) at time \(t\)
\(P(C,t)\) is a solution of the master equation

\[ \frac{\partial P(C,t)}{\partial t}=\sum_{C':C'\neq C}P(C',t)W(C'\to C)-\left(\sum_{C':C'\neq C}W(C\to C')\right)P(C,t) \]

Master equation for asymmetric simple exclusion process

key concepts

spin chain

master equation and the formalism using the Hamiltonian of the spin chain
Heisenberg spin chain model can be viewed as a exclusion process (time evolution)

critical exponent

relaxation time \(\tau\) towards equilibrium
spatial correlation length \(\xi\)
dynamical critical exponent \(z\) given by \(\tau \sim \xi^z\)
for one-dimensional quantum spin chains \(\tau \sim L^z\) where \(L\) is the length of the spin chain

Bethe ansatz

\(\tau\) is dominated by the eigenvalue of the Hamiltonian with the smallest real part

thus the finite size analysis of the Hamiltonian gives

\[ \Re(E_1)\sim \frac{1}{L^z} \]

so we need to compute \(E_1\) to get \(z\)
this is where the Bethe ansatz comes in

two species model

two species asymmetric diffusion model that describes two species and vacancies diffusing asymmetrically on a one-dimensional lattice
use algebraic Bethe Ansatz
find the finite-size scaling behavior of the lowest lying eigenstates of the quantum Hamiltonian describing the model and compute the dynamical critical exponent
Multi-species asymmetric simple exclusion process
