摘要：

The thermalization process of the 2D Kitaev model is studied within the Markovian weak coupling approximation. It is shown that its largest relaxation time is bounded from above by a constant independent of the system size and proportional to exp(2 Delta/kT), where Delta is an energy gap over the fourfold degenerate ground state. This means that the 2D Kitaev model is not an example of a memory, neither quantum nor classical.
