Doping a Mott insulator: Physics of high-temperature superconductivity

  title={Doping a Mott insulator: Physics of high-temperature superconductivity},
  author={Patrick A. Lee and Naoto Nagaosa and Xiao-Gang Wen},
  journal={Reviews of Modern Physics},
This article reviews the physics of high-temperature superconductors from the point of view of the doping of a Mott insulator. The basic electronic structure of cuprates is reviewed, emphasizing the physics of strong correlation and establishing the model of a doped Mott insulator as a starting point. A variety of experiments are discussed, focusing on the region of the phase diagram close to the Mott insulator (the underdoped region) where the behavior is most anomalous. The normal state in… 
The high temperature superconductivity in cuprates: physics of the pseudogap region
Abstract We discuss the physics of the high temperature superconductivity in hole doped copper oxide ceramics in the pseudogap region. Starting from an effective reduced Hamiltonian relevant to the
Self-Doping and the Mott-Kondo Scenario for Infinite-Layer Nickelate Superconductors
We give a brief review of the Mott-Kondo scenario and its consequence in the recently-discovered infinite-layer nickelate superconductors. We argue that the parent state is a self-doped Mott
From high temperature superconductivity to quantum spin liquid: progress in strong correlation physics
This review gives a rather general discussion of high temperature superconductors as an example of a strongly correlated material. The argument is made that in view of the many examples of
Disappearance of nodal gap across the insulator-superconductor transition in a copper-oxide superconductor.
High-resolution angle-resolved photoemission measurement on heavily underdoped Bi₂Sr₁-xLaxCuO(₆+δ) system reveals a clear insulator-superconductor transition at a critical doping level of ~0.10, which clearly signal a close connection between the nodal gap, antiferromagnetism and superconductivity.
Fluctuating superconductivity in organic molecular metals close to the Mott transition
This work argues that a key pseudogap phenomenon—fluctuating superconductivity occurring substantially above the transition temperature—could be induced by the proximity of a Mott-insulating state and finds that a fluctuating regime develops as t/U decreases and the role of Coulomb correlations increases.
Influence of magnetism and correlation on the spectral properties of doped Mott insulators
Unravelling the nature of doping-induced transition between a Mott insulator and a weakly correlated metal is crucial to understanding novel emergent phases in strongly correlated materials. For this
Electric field effect and superconducting–insulating transition in '123' cuprate superconductors
The physics of high critical temperature superconductors (HTS) remains a fascinating but undisclosed issue in condensed matter. One of the most interesting topics is the transition from the
Recent models for the occurrence of high-temperature superconductivity predict that the superconducting transition of underdoped cuprates is determined by the phase fluctuations of the order
Strongly correlated superconductivity arising in a pseudogap metal
We solve by dynamical mean field theory a toy model that has a phase diagram strikingly similar to that of high-${T}_{c}$ superconductors: a bell-shaped superconducting region adjacent to the Mott

Importance of phase fluctuations in superconductors with small superfluid density
THE superconducting state of a metal is characterized by a complex order parameter with an amplitude and a phase. In the BCS-Eliashberg mean-field theory1, which is a very good approximation for
Electrodynamics of high- T c superconductors
Recent studies of the electromagnetic response of high-Tc superconductors using terahertz, infrared, and optical spectroscopies are reviewed. In combination these experimental techniques provide a
Non-Fermi-liquid behavior and d-wave superconductivity near the charge-density-wave quantum critical point
AbstractA scenario is presented, in which the presence of a quantum critical point due to formation of incommensurate charge density waves accounts for the basic features of the high temperature
Destruction of the Fermi surface in underdoped high-Tc superconductors
The Fermi surface—the set of points in momentum space describing gapless electronic excitations—is a central concept in the theory of metals. In this context, the normal ‘metallic’ state of the
Big, Fast Vortices in the d-RVB theory of High Temperature Superconductivity
The effect of proximity to a Mott insulating phase on the superflow properties of a d-wave superconductor is studied using the slave-boson U(1)-gauge-theory model. The model has two limits
Nodal Liquid Theory of the Pseudo-Gap Phase of High-Tc Superconductors
We introduce and study the nodal liquid, a novel zero-temperature quantum phase obtained by quantum-disordering a d-wave superconductor. It has numerous remarkable properties which lead us to suggest
Metal-insulator transitions
Metal-insulator transitions are accompanied by huge resistivity changes, even over tens of orders of magnitude, and are widely observed in condensed-matter systems. This article presents the
An unusual isotope effect in a high-transition-temperature superconductor
A detailed comparison of the electron dynamics of Bi2212 samples containing different oxygen isotopes is provided, using angle-resolved photoemission spectroscopy, to suggest that these results can be explained in a dynamic spin-Peierls picture, where the singlet pairing of electrons and the electron–lattice coupling mutually enhance each other.
Spectroscopic evidence for a pseudogap in the normal state of underdoped high-Tc superconductors
IT is well known that BCS mean-field theory is remarkably successful in describing conventional superconductors. A central concept of BCS theory is the energy gap in the electronic excitation
