The Fractal Dimension of the Spectrum of the Fibonacci Hamiltonian
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

Quantitative study of lubricant puddling at the head/disk interface
This paper presents a new methodology to quantify the micro-level lubricant accumulation (lubricant puddling) on a magnetic recording hard disk for flyability testing. After flying over the disk for certain p...

Spectral approximation of banded Laurent matrices with localized random perturbations
This paper explores the relationship between the spectra of perturbed infinite banded Laurent matricesL(a)+K and their approximations by perturbed circulant matricesC n (a)+P n KP n for largen. The entriesK jk of...
