In this talk I will show how one can describe evolution of strongly interacting quantum systems using classical Hamiltonian equations of motion. This becomes possible if we increase the phase space dimensionality by introducing hidden variables. In particular, I will demonstrate that dynamics of interacting fermions can be efficiently simulated if we describe classical phase space through strings (bilinears), which connect all possible single-particle states. In this language dynamics of SYK model actively used to study quantum chaos becomes fully classical.
