Continuous spectrum for a class of smooth mixing Schrödinger operators

Bassam Fayad, Yanhui Qu

We give the first example of a smooth volume preserving mixing dynamical system such that the discrete Schrödinger operators on the line defined with a potential generated by this…

Exact-dimensional property of density of states measure of Sturm Hamiltonian

Yanhui Qu

For frequency $α$ of bounded type and coupling $λ > 20$ , we show that the density of states measure $\NN_{α,λ}$ of the related Sturm Hamiltonian is exact upper and lower dimensional,…

"Mixed spectral nature" of Thue--Morse Hamiltonian

Qinghui Liu, Yanhui Qu, Xiao Yao

We find three dense subsets $Σ_{I}, Σ_{I I}$ and $Σ_{I I I}$ of the spectrum of the Thue-Morse Hamiltonian, such that each energy in $Σ_{I}$ is extended, each energy in $Σ_{I I}$ is pseudo-…
