Query: Lattice supersymmetry and order-disorder coexistence in the tricritical
  Ising model   We introduce and analyze a quantum spin/Majorana chain with a tricritical
Ising point separating a critical phase from a gapped phase with order-disorder
coexistence. We show that supersymmetry is not only an emergent property of the
scaling limit, but manifests itself on the lattice. Namely, we find explicit
lattice expressions for the supersymmetry generators and currents. Writing the
Hamiltonian in terms of these generators allows us to find the ground states
exactly at a frustration-free coupling. These confirm the coexistence between
two (topologically) ordered ground states and a disordered one in the gapped
phase. Deforming the model by including explicit chiral symmetry breaking, we
find the phases persist up to an unusual chiral phase transition where the
supersymmetry becomes exact even on the lattice.
