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 …

Quantum spin liquids may be considered'quantum disordered'ground states of spin systems,
in which zero-point fluctuations are so strong that they prevent conventional magnetic long …

Spin liquids are collective phases of quantum matter that have eluded discovery in
correlated magnetic materials for over half a century. Theoretical models of these enigmatic …

Muon spin relaxation (μ SR) experiments on single crystals of the structurally perfect
triangular antiferromagnet YbMgGaO 4 indicate the absence of both static long-range …

We review the interplay of frustration and strong electronic correlations in quasi-two-
dimensional organic charge transfer salts, such as (BEDT-TTF) 2 X and Et n Me 4− n Pn [Pd …

Samarium hexaboride is a classic three-dimensional mixed valence system with a high-
temperature metallic phase that evolves into a paramagnetic charge insulator below 40 K. A …

Experiments on quantum materials have uncovered many interesting quantum phases
ranging from superconductivity to a variety of topological quantum matter including the …

The cradle of quantum spin liquids, triangular antiferromagnets show strong proclivity to
magnetic order and require deliberate tuning to stabilize a spin-liquid state. In this brief …

Recent developments in research into superconductivity in organic materials are reviewed.
In the epoch-defining quasi-one-dimensional TMTSF superconductors with T c∼ 1 K, T c …

The long search for insulating materials that possess low-energy quasiparticles carrying
electron's quantum numbers except charge—inspired by the neutral spin-1/2 excitations, the …
