This is an introductory review of the physics of quantum spin liquid states. Quantum
magnetism is a rapidly evolving field, and recent developments reveal that the ground states …

Topological quantum computation has emerged as one of the most exciting approaches to
constructing a fault-tolerant quantum computer. The proposal relies on the existence of …

This article reviews the physics of high-temperature superconductors from the point of view
of the do** of a Mott insulator. The basic electronic structure of cuprates is reviewed …

Presenting the physics of the most challenging problems in condensed matter using the
conceptual framework of quantum field theory, this book is of great interest to physicists in …

A concept—quantum order—is introduced to describe a new kind of orders that generally
appear in quantum states at zero temperature. Quantum orders that characterize the …

We study the quantum dimer model on the triangular lattice, which is expected to describe
the singlet dynamics of frustrated Heisenberg models in phases where valence bond …

We develop a new theoretical framework for describing and analyzing exotic phases of
strongly correlated electrons which support excitations with fractional quantum numbers …

We report on a systematic study of two-dimensional, periodic, frustrated Ising models with
quantum dynamics introduced via a transverse magnetic field. The systems studied are the …

We find all the exact eigenstates and eigenvalues of a spin-1/2 model on square lattice: H=
16 g∑ i S iy S i+ x^ x S i+ x^+ y^ y S i+ y^ x. We show that the ground states for g< 0 and g> …

Quantum dimer models are believed to capture the essential physics of antiferromagnetic
phases dominated by short-ranged valence bond configurations. We show that these …
