The simplest quantum model supporting the Kibble-Zurek mechanism of   topological defect production: Landau-Zener transitions from a new   perspective
  It is shown that dynamics of the Landau-Zener model can be accurately described in terms of the Kibble-Zurek theory of the topological defect production in nonequilibrium phase transitions. The simplest quantum model exhibiting the Kibble-Zurek mechanism is presented. A new intuitive description of Landau-Zener dynamics is found.
