Flux crystals, Majorana metals, and flat bands in exactly solvable spin-orbital liquids
Sreejith Chulliparambil, Lukas Janssen, Matthias Vojta +2
Spin-orbital liquids are quantum disordered states in systems with entangled spin and orbital degrees of freedom. We study exactly solvable spin-orbital models in two dimensions wi…

Fractionalized fermionic quantum criticality in spin-orbital Mott insulators
Urban F. P. Seifert, Xiao-Yu Dong, Sreejith Chulliparambil +3
We study transitions between topological phases featuring emergent fractionalized excitations in two-dimensional models for Mott insulators with spin and orbital degrees of freedom…

Microscopic models for Kitaev's sixteenfold way of anyon theories
Sreejith Chulliparambil, Urban F. P. Seifert, Matthias Vojta +2
In two dimensions, the topological order described by gauge theory coupled to free or weakly interacting fermions with a nonzero spectral Chern number is classif…
