The Dry Ten Martini Problem for subcritical Type I operators

Lingrui Ge

We supply the details of the subcritical dry Ten Martini statement announced in [6, Remark 1.3]: for every irrational frequency, every subcritical Type I energy with resonant rotat…

Kotani theory, Puig's argument, and stability of The Ten Martini Problem

Lingrui Ge, Svetlana Jitomirskaya, Jiangong You

We solve the ten martini problem (Cantor spectrum with no condition on irrational frequencies, previously only established for the almost Mathieu) for a large class of one-frequenc…

Multiplicative Jensen's formula and quantitative global theory of one-frequency Schrödinger operators

Lingrui Ge, Svetlana Jitomirskaya, Jiangong You +1

We introduce the concept of dual Lyapunov exponents, leading to a multiplicative version of the classical Jensen's formula for one-frequency analytic Schrödinger cocycles. This for…

Hofstadter butterflies and metal/insulator transitions for moiré heterostructures

Simon Becker, Lingrui Ge, Jens Wittsten

We consider a tight-binding model recently introduced by Timmel and Mele for strained moiré heterostructures. We consider two honeycomb lattices to which layer antisymmetric shear…
