Query: Fractionalized fermionic quantum criticality in spin-orbital Mott
  insulators   We study transitions between topological phases featuring emergent
fractionalized excitations in two-dimensional models for Mott insulators with
spin and orbital degrees of freedom. The models realize fermionic quantum
critical points in fractionalized Gross-Neveu$^\ast$ universality classes in
(2+1) dimensions. They are characterized by the same set of critical exponents
as their ordinary Gross-Neveu counterparts, but feature a different energy
spectrum, reflecting the nontrivial topology of the adjacent phases. We
exemplify this in a square-lattice model, for which an exact mapping to a
$t$-$V$ model of spinless fermions allows us to make use of large-scale
numerical results, as well as in a honeycomb-lattice model, for which we employ
$\epsilon$-expansion and large-$N$ methods to estimate the critical behavior.
Our results are potentially relevant for Mott insulators with $d^1$ electronic
configurations and strong spin-orbit coupling, or for twisted bilayer
structures of Kitaev materials.
