Interacting spin systems are of fundamental relevance in different areas ofphysics, as well as in quantum information science, and biology. These spinmodels represent the simplest, yet not fully understood, manifestation ofquantum many-body systems. An important outstanding problem is the efficientnumerical computation of dynamics in large spin systems. Here we propose a newsemiclassical method to study many-body spin dynamics in generic spin latticemodels. The method is based on a discrete Monte Carlo sampling in phase-spacein the framework of the so-called truncated Wigner approximation. Comparisonswith analytical and numerically exact calculations demonstrate the power of thetechnique. They show that it correctly reproduces the dynamics of one- andtwo-point correlations and spin squeezing at short times, thus capturingentanglement. Our results open the possibility to study the quantum dynamicsaccessible to recent experiments in regimes where other numerical methods areinapplicable.
