Query: Zigzag and Checkerboard Magnetic Patterns in Orbitally Directional
  Double-Exchange Systems   We analyze a $t_{2g}$ double-exchange system where the orbital directionality
of the itinerant degrees of freedom is a key dynamical feature that
self-adjusts in response to doping and leads to a phase diagram dominated by
two classes of ground-states with zigzag and checkerboard patterns. The
prevalence of distinct orderings is tied to the formation of orbital molecules
that in one-dimensional paths make insulating zigzag states kinetically more
favorable than metallic stripes, thus allowing for a novel doping-induced
metal-to-insulator transition. We find that the basic mechanism that controls
the magnetic competition is the breaking of orbital directionality through
structural distortions and highlight the consequences of the interorbital
Coulomb interaction.
