Fibonacci哈密顿量谱的分形维数

The Fractal Dimension of the Spectrum of the Fibonacci Hamiltonian

David Damanik, Mark Embree, Anton Gorodetski, Serguei Tcheremchantsev

摘要:

我们研究了斐波那契哈密顿量的频谱,并证明了其分形维数在大耦合制度的上限和下限。这些界限表明,作为$λ\to \infty$,$\dim (σ(H_λ)) \cdot \log λ$收敛到一个显式常数($\approx 0.88137$)。我们还讨论了这些结果的后果,根据薛定谔动力学产生的斐波那契哈密顿量的波包的传播速率的演变。

英文摘要:

We study the spectrum of the Fibonacci Hamiltonian and prove upper and lower bounds for its fractal dimension in the large coupling regime. These bounds show that as $λ\to \infty$, $\dim (σ(H_λ)) \cdot \log λ$ converges to an explicit constant ($\approx 0.88137$). We also discuss consequences of these results for the rate of propagation of a wavepacket that evolves according to Schrödinger dynamics generated by the Fibonacci Hamiltonian.
