Transfer Operators, Canonical Center Dynamics, and Spectral Applications for Long-Range Operators

Xianzhe Li, Zhenfu Wang, Jiangong You +1

We introduce an operator-theoretic framework for long-range operators over general dynamical systems with analytic hopping and small potential. By establishing a partially hyperbol…

Monotonicity, global symplectification and the stability of Dry Ten Martini Problem

Xianzhe Li, Disheng Xu, Qi Zhou

We prove that, for every irrational frequency and every analytic Type I potential, each supercritical spectral energy satisfying the gap-labelling condition is an endpoint of an op…

Log-Hausdorff multifractality of the absolutely continuous spectral measure of the almost Mathieu operator

Jie Cao, Xianzhe Li, Baowei Wang +1

This paper focuses on the fractal characteristics of the absolutely continuous spectral measure of the subcritical almost Mathieu operator (AMO) and Diophantine frequency. In parti…

Exact local distribution of the absolutely continuous spectral measure

Xianzhe Li, Jiangong You, Qi Zhou

It is well-established that the spectral measure for one-frequency Schrödinger operators with Diophantine frequencies exhibits optimal -Hölder continuity within the absolutely…

Stability of Spectral Types of Quasi-Periodic Schrödinger Operators With Respect to Perturbations by Decaying Potentials

David Damanik, Xianzhe Li, Jiangong You +1

We consider perturbations of quasi-periodic Schrödinger operators on the integer lattice with analytic sampling functions by decaying potentials and seek decay conditions under whi…
