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 …

Electron correlation and spin frustration are among the central issues in condensed matter
physics, and their interplay is expected to bring about exotic phases with both charge and …

Quantum computers, though not yet available on the market, will revolutionize the future of
information processing. Quantum computers for special purposes like quantum simulators …

The antiferromagnetic spin-1/2 Heisenberg model on a kagome lattice is one of the most
paradigmatic models in the context of spin liquids, yet the precise nature of its ground state …

We use the density matrix renormalization group to perform accurate calculations of the
ground state of the nearest-neighbor quantum spin S= 1/2 Heisenberg antiferromagnet on …

We perform a density-matrix renormalization group (DMRG) study of the S= 1 2 Heisenberg
antiferromagnet on the kagome lattice to identify the conjectured spin liquid ground state …

We review recent developments in the physics of ultracold atomic and molecular gases in
optical lattices. Such systems are nearly perfect realisations of various kinds of Hubbard …

We have performed thermodynamic and neutron scattering measurements on the S= 1/2
kagomé lattice antiferromagnet ZnCu 3 (OH) 6 Cl 2. The susceptibility indicates a Curie …

The syntheses and magnetic susceptibilities of a pure series of rare copper minerals from
the atacamite family with general formula Zn x Cu4-x (OH) 6Cl2 (0≤ x≤ 1) are reported. The …

The nature of quantum spin liquids, a novel state of matter where strong quantum
fluctuations destroy the long-range magnetic order even at zero temperature, is a long …
