Discovery of Dynamics Using Linear Multistep Methods

Rachael Keller, Qiang Du

Linear multistep methods (LMMs) are popular time discretization techniques for the numerical solution of differential equations. Traditionally they are applied to solve for the sta…

Spectral band degeneracies of $\frac{π}{2} -$ rotationally invariant periodic Schrödinger operators

Rachael T. Keller, Jeremy L. Marzuola, Braxton Osting +1

The dynamics of waves in periodic media is determined by the band structure of the underlying periodic Hamiltonian. Symmetries of the Hamiltonian can give rise to novel properties…
