Query: The Orbitally Selective Mott Phase in Electron Doped Twisted TMDs: A
  Possible Realization of the Kondo Lattice Model   Moir\'e super-potentials in two-dimensional materials allow unprecedented
control of the ratio between kinetic and interaction energy. By this, they pave
the way to study a wide variety of strongly correlated physics under a new
light. In particular, the transition metal dichalcogenides (TMDs) are promising
candidate "quantum simulators" of the Hubbard model on a triangular lattice.
Indeed, Mott and generalized Wigner crystals have been observed in such
devices. Here we theoretically propose to extend this model into the
multi-orbital regime by focusing on electron doped systems at filling higher
than 2. As opposed to hole bands, the electronic bands in TMD materials include
two, nearly degenerate species, which can be viewed as two orbitals with
different effective mass and binding energy. Using realistic band-structure
parameters and a slave-rotor mean-field theory, we find that an orbitally
selective Mott (OSM) phase can be stabilized over a wide range of fillings,
where one band is locked in a commensurate Mott state, while the other remains
itinerant with variable density. This scenario thus, realizes the basic
ingredients in the Kondo lattice model: A periodic lattice of localized
magnetic moments interacting with metallic states. We also discuss possible
experimental signatures of the OSM state.
