量子Baker映射遍历性的探讨

The Approach to Ergodicity in the Quantum Baker's Map

Andrew Jordan, Mark Srednicki

摘要:

我们研究了广义贝克映射的量子力学。我们表明,吕勒共振(这支配的方法遍历的经典分布相空间)也出现在量子关联函数的观测在不同的时间,因此控制的统计方差矩阵元素的观测(在量子时间演化算子的本征态的基础上)。我们用数值结果说明了这一点。

英文摘要:

We study the quantum mechanics of a generalized version of the baker's map. We show that the Ruelle resonances (which govern the approach to ergodicity of classical distributions on phase space) also appear in the quantum correlation functions of observables at different times, and hence control the statistical variance of matrix elements of observables (in the basis of eigenstates of the quantum time evolution operator). We illustrate this with numerical results.
