经典非调和格点系统的Lieb-Robinson界

Lieb-Robinson bounds for classical anharmonic lattice systems

Hillel Raz, Robert Sims

摘要:

我们证明局部估计,在Lieb-Robinson界的形式,经典的振荡器系统定义在一个格子上。我们的结果适用于具有长程相互作用的调和系统和各种非调和扰动。非调和估计适用于一类特殊的可观测量,外尔函数,和随之而来的边界不仅是独立的体积,而且初始条件。

英文摘要:

We prove locality estimates, in the form of Lieb-Robinson bounds, for classical oscillator systems defined on a lattice. Our results hold for the harmonic system and a variety of anharmonic perturbations with long range interactions. The anharmonic estimates are applicable to a special class of observables, the Weyl functions, and the bounds which follow are not only independent of the volume but also the initial condition.
