Quantitative Unique Continuation on Simplex and $Z^{n}$

Shihe Liu, Yunfeng Shi, Zhifei Zhang

In this work, we establish the quantitative unique continuation on both $n$ -dimensional simplex lattice $Δ_{N}^{(n)}$ and $Z^{n}$ for arbitrary $n \geq 3$ .

Anderson localized states for the nonlinear Maryland model on $Z^{d}$

Shihe Liu, Yunfeng Shi, Zhifei Zhang

In this paper, we investigate Anderson localization for a nonlinear perturbation of the Maryland model $H = ε I^ + cot I ¨ (I^¸ + j \cdot I^\pm) I^´_{j, j^{'}}$ on $Z^{d}$ . Specificall…
