Abstract
The orbital-selective Mott phase of multiorbital Hubbard models has been extensively analyzed before
using static and dynamical mean-field approximations. In parallel, the properties of block states
(antiferromagnetically coupled ferromagnetic spin clusters) in Fe-based superconductors have also been
much discussed. The present effort uses numerically exact techniques in one-dimensional systems to report
the observation of block states within the orbital-selective Mott phase regime, connecting two seemingly
independent areas of research, and providing analogies with the physics of double-exchange models.
