We construct explicit examples of microscopic models that stabilize a variety of fractionalized phases of strongly correlated systems in a spatial dimension larger than one, and in a zero external magnetic field. These include models of charge fractionalization in boson-only systems, and various kinds of spin-charge separation in electronic systems. We determine the excitation spectrum, and show the consistency with that expected from field theoretic descriptions of fractionalization. Our results are further substantiated by direct numerical calculation of the phase diagram of one of the models.
