Query: Magnon Landau levels and emergent supersymmetry in strained
  antiferromagnets   Inhomogeneous strain applied to lattice systems can induce artificial gauge
fields for particles moving on this lattice. Here we demonstrate how to
engineer a novel state of matter, namely an antiferromagnet with a Landau-level
excitation spectrum of magnons. We consider a honeycomb-lattice Heisenberg
model and show that triaxial strain leads to equally spaced pseudo-Landau
levels at the upper end of the magnon spectrum, with degeneracies
characteristic of emergent supersymmetry. We also present a particular strain
protocol which induces perfectly quantized magnon Landau levels over the whole
bandwidth. We discuss experimental realizations and generalizations.
