We explore theoretically the notion that the underdoped cuprates may be viewed as doped $U(1)$ spin liquid Mott insulators. We pursue a conceptually clear version of this idea that naturally incorporates several aspects of the phenomenology of the cuprates. We argue that the low-doping region may be fruitfully discussed in terms of the universal physics associated with a chemical-potential-tuned Mott transition between a $U(1)$ spin liquid insulator and a $d$-wave superconductor. A precise… Expand
Dual 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 theExpand
The pseudogap: friend or foe of high T c ?
Although nineteen years have passed since the discovery of high temperature cuprate superconductivity 1, there is still no consensus on its physical origin. This is in large part because of a lack ofExpand
Doping a Mott insulator: Physics of high-temperature superconductivity
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 theExpand
Neel order, quantum spin liquids, and quantum criticality in two dimensions
This paper is concerned with the possibility of a direct second-order transition out of a collinear Neel phase to a paramagnetic spin liquid in two-dimensional quantum antiferromagnets. Contrary toExpand

Topological superconductivity in the Kondo-Kitaev model
We investigate possible topological superconductivity in the Kondo-Kitaev model on the honeycomb lattice, where the Kitaev spin liquid is coupled to conduction electrons via the Kondo coupling. WeExpand
Mobile holes in frustrated quantum magnets and itinerant fermions on frustrated geometries
At commensurate electron fillings and in the presence of strong Coulomb repulsion, geometrical frustration can also manifests itself as an extensive degeneracy of the classical ground-state manifold providing profound similarities with the field of quantum frustrated magnetism. Expand
Hole dynamics in an antiferromagnet across a deconfined quantum critical point
We study the effects of a small density of holes, δ, on a square lattice antiferromagnet undergoing a continuous transition from a Neel state to a valence bond solid at a deconfined quantum criticalExpand
Deconfined criticality and a gapless Z2 spin liquid in the square lattice antiferromagnet
The theory for the vanishing of Néel order in the spin S = 1/2 square lattice antiferromagnet has been the focus of attention for many decades. A consensus appears to have emerged in recent numericalExpand

Theory of spin excitations in undoped and underdoped cuprates
Abstract We consider the magnetic properties of high T c cuprates from a gauge theory point of view, with emphasis on the underdoped regime. Underdoped cuprates possess certain antiferromagneticExpand

Spin correlations in the algebraic spin liquid: Implications for high-Tc superconductors
We propose that underdoped high-T c superconductors are described by an algebraic spin liquid (ASL) at high energies, which undergoes a spin-charge recombination transition at low energies. The spinExpand
