Kitaev二维模型中的热化现象

On thermalization in Kitaev's 2D model

R. Alicki, M. Fannes, M. Horodecki

摘要:

在马尔可夫弱耦合近似下研究了二维Kitaev模型的热化过程。它示出,它的最大弛豫时间是有界的从上面由一个常数的系统的大小无关,并成比例的$\exp(2Δ/kT)$其中$Δ$是一个能隙超过4倍简并基态。这意味着2D Kitaev模型不是记忆的例子,既不是量子的也不是经典的。

英文摘要:

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 $\exp(2Δ/kT)$ where $Δ$ is an energy gap over the 4-fold degenerate ground state. This means that the 2D Kitaev model is not an example of a memory, neither quantum nor classical.
