Dynamical Ginzburg criterion for the quantum-classical crossover of the Kibble-Zurek mechanism

Understand

We introduce a simple criterion for lattice models to predict quantitatively the crossover between the classical and the quantum scaling of the Kibble-Zurek mechanism, as the one observed in a quantum $\phi^4$-model on a 1D lattice [Phys.
