Dispersive decay bounds for the SSH model on the half-line
Remy Kassem, Amir Sagiv, Michael I. Weinstein
We study the Schrödinger flow for the SSH model, a class of self-adjoint discrete dimer lattice Hamiltonians on the half-line. Using oscillatory integral techniques, we prove disp…

Continuum honeycomb Schrödinger operators with incommensurate line defects
Pierre Amenoagbadji, Michael I. Weinstein
We study wave propagation in 2D honeycomb structures with a non-commensurate or ``irrational'' line defect or edge. Our model is a Schrödinger operator which interpolates, across t…

Pseudo-magnetism in a strained discrete honeycomb lattice
Xuenan Li, Michael I. Weinstein
Slowly varying nonuniform strains of non-magnetic wave propagating media with honeycomb symmetry induce an effective- or pseudo-magnetic field, a phenomenon observed first in graph…
