阻尼量子混沌系统的谱理论

Spectral theory of damped quantum chaotic systems

Stéphane Nonnenmacher

摘要:

研究了紧致黎曼流形上阻尼波动方程的谱分布,特别是在度量为负曲率的情况下,其测地线流为Anosov。主要的应用是获得条件(在$X$上的测地线流和阻尼函数方面),至少对于足够平滑的初始数据,波的能量以指数方式快速衰减。我们审查各种估计的高频谱的动态定义的数量,如时间平均阻尼的值分布。我们还提出了一个新的条件的光谱间隙,取决于一组最小阻尼轨迹。

英文摘要:

We investigate the spectral distribution of the damped wave equation on a compact Riemannian manifold, especially in the case of a metric of negative curvature, for which the geodesic flow is Anosov. The main application is to obtain conditions (in terms of the geodesic flow on $X$ and the damping function) for which the energy of the waves decays exponentially fast, at least for smooth enough initial data. We review various estimates for the high frequency spectrum in terms of dynamically defined quantities, like the value distribution of the time-averaged damping. We also present a new condition for a spectral gap, depending on the set of minimally damped trajectories.
