Sharp decay rate for eigenfunctions of perturbed periodic Schrödinger operators

Wencai Liu, Rodrigo Matos, John N. Treuer

This paper investigates uniqueness results for perturbed periodic Schrödinger operators on $Z^{d}$ . Specifically, we consider operators of the form $H = - Δ + V + v$ , where $Δ…

Floquet Isospectrality of the Zero Potential for Discrete Periodic Schrödinger Operators

Matthew Faust, Wencai Liu, Rodrigo Matos +5

Let $Γ = q_{1} Z \oplus q_{2} Z \oplus \dots \oplus q_{d} Z$ , with $q_{j} \in (Z^{+})^{d}$ for each $j \in {1, \dots, d}$ , and denote by $Δ$ the discrete Laplacian…

Algebraic Properties of the Fermi Variety for Periodic Graph Operators

Jake Fillman, Wencai Liu, Rodrigo Matos

We present a method to estimate the number of irreducible components of the Fermi varieties of periodic Schrödinger operators on graphs in terms of suitable asymptotics. Our main t…
