Memory effects and time correlations in Kardar Parisi Zhang growth via integrability.

Pierre Le Doussal, ENS Paris

We review the 1D KPZ class of stochastic growth. One time observables are by now well characterized, but multi-time correlations are still mostly an open problem. Using replica Bethe ansatz methods we obtain analytically the two time correlations in several limits. The predictions are found in excellent agreement with experiments. An interesting memory effect is found and quantified when the growth occurs in an expanding geometry. Based on the 3 papers {\\bf Tail of the two-time height distribution for KPZ growth in one dimension} Jacopo de Nardis, Pierre Le Doussal, arXiv:1612.08695, J. Stat.
