Doped Mott insulators are insulators: hole localization in the cuprates.
We demonstrate that a Mott insulator lightly doped with holes is still an insulator at low temperature even without disorder. Hole localization obtains because the chemical potential lies in a pseudogap which has a vanishing density of states at zero temperature. The energy scale for the pseudogap is set by the nearest-neighbor singlet-triplet splitting. As this energy scale vanishes if transit...
متن کاملElectronic Liquid Crystal Phases in Hole Doped Mott Insulators
Theoretical, numerical, and experimental studies have suggested the existence of ‘striped’ electronic phases in doped antiferromagnets such as the high temperature superconductors. We survey the literature and summarize the results.
متن کاملd-Wave superconductivity in doped Mott insulators
The effect of proximity to a Mott insulating phase on the charge transport properties of a superconductor is determined. An action describing the low energy physics is formulated and different scenarios for the approach to the Mott phase are distinguished by different variation with doping of the parameters in the action. A crucial issue is found to be the doping dependence of the quasiparticle...
متن کاملTheory for slightly doped antiferromagnetic mott insulators.
New trial wave functions, constructed explicitly from the unique Mott insulating state with antiferromagnetic order, are proposed to describe the ground state of a Mott insulator slightly doped with holes or electrons. A rigid band is observed as charged quasiparticles with well-defined momenta being realized in these states. These states have much less superconducting correlations than previou...
متن کاملDual vortex theory of doped Mott insulators
We present a general framework for describing the quantum phases obtained by doping paramagnetic Mott insulators on the square lattice. The undoped insulators are efficiently characterized by the projective transformations of various fields under the square lattice space group (the PSG). We show that the PSG also imposes powerful constraints on the doped system, and on the effective action for ...
