Query: Quantum phase transition between orbital-selective Mott states in Hund's
  metals   We report a quantum phase transition between orbital-selective Mott states,
with different localized orbitals, in a Hund's metals model. Using the density
matrix renormalization group, the phase diagram is constructed varying the
electronic density and Hubbard $U$, at robust Hund's coupling. We demonstrate
that this transition is preempted by charge fluctuations and the emergence of
free spinless fermions, as opposed to the magnetically-driven Mott transition.
The Luttinger correlation exponent is shown to have a universal value in the
strong-coupling phase, whereas it is interaction dependent at intermediate
couplings. At weak coupling we find a second transition from a normal metal to
the intermediate-coupling phase.
