Long-range correlations in the out-of-equilibrium dynamics

After discussing how space-time dualities cannot in general break the entanglement barrier as discussed in [1]
I will explain how in [2] we show that the entanglement barrier can be circumvented  by identifying long-range entanglement and trading it for mixture
In this way  we can design a novel class of  algorithms based on tensor networks that allow to predict the long-time evolution of local observables with a finite computational cost.
