非简谐势阱中的混合

Mixing in an anharmonic potential well

Matías Moreno, Paola Rioseco, Hanne Van Den Bosch

摘要:

证明了可积系统的Liouville方程解的相空间混合性。在自然非调和性条件下,得到了速率为$\langle \mathrm{time} \rangle^{-1}$的分布函数的弱收敛性。在一维中,我们还研究了这种条件在一定能量下失败的情况,表明混合仍然成立,但速度较慢。当条件成立且函数具有较高的正则性时,速率可以更快。

英文摘要:

We prove phase-space mixing for solutions to Liouville's equation for integrable systems. Under a natural non-harmonicity condition, we obtain weak convergence of the distribution function with rate $\langle \mathrm{time} \rangle^{-1}$. In one dimension, we also study the case where this condition fails at a certain energy, showing that mixing still holds but with a slower rate. When the condition holds and functions have higher regularity, the rate can be faster.
