Abstract (EN)
We study the one-dimensional asymmetric simple exclusion process on the lattice {1,. .. , N } with creation/annihilation at the boundaries. The boundary rates are time dependent and change on a slow time scale N^a with a > 0. We prove that at the time scale N^{1+a} the system evolves quasi-statically with a macroscopic density profile given by the entropy solution of the stationary Burgers equation with boundary densities changing in time, determined by the corresponding microscopic boundary rates. We consider two different types of boundary rates: the "Liggett boundaries" that correspond to the projection of the infinite dynamics, and the reversible boundaries, that correspond to the contact with particle reservoirs in equilibrium. The proof is based on the control of the Lax boundary entropy-entropy flux pairs and a coupling argument.
