Origin of the Mott Gap

We show exactly that the only charged excitations that exist in the strong-coupling limit of the half-filled Hubbard model are gapped composite excitations generated by the dynamics of the charge \(2e\) boson that appears upon explicit integration of the high-energy scale. At every momentum, such ex...
