Scaling Estimates for Solutions and Dynamical Lower Bounds on Wavepacket Spreading
摘要:
我们建立量子动力学的离散一维薛定谔算子的情况下,除了幂律上限的解决方案对应的能量在频谱上的下限,也有以下的标度律。因此,我们得到改进的动力学结果的斐波那契哈密顿量和相关的模型。
英文摘要:
We establish quantum dynamical lower bounds for discrete one-dimensional Schrödinger operators in situations where, in addition to power-law upper bounds on solutions corresponding to energies in the spectrum, one also has lower bounds following a scaling law. As a consequence, we obtain improved dynamical results for the Fibonacci Hamiltonian and related models.
