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 …

The exactly solvable Kitaev model on the honeycomb lattice has recently received
enormous attention linked to the hope of achieving novel spin-liquid states with …

Muons are particles with a spin of ½ that can be implanted into a wide range of condensed
matter materials to act as a local probe of the surrounding atomic environment …

We have carried out muon spin relaxation and rotation measurements on the newly
discovered kagome metal KV 3 Sb 5, and find a local field dominated by weak magnetic …

In condensed matter physics there is a novel phase termed 'quantum spin liquid', in which
strong quantum fluctuations prevent long-range magnetic order from being estab lished, and …

Complex oxides with 4 d and 5 d transition-metal ions recently emerged as a new paradigm
in correlated electron physics, due to the interplay between spin–orbit coupling and electron …

It has long been hoped that spin liquid states might be observed in materials that realize the
triangular-lattice Hubbard model. However, weak spin–orbit coupling and other small …

Kondo impurities provide a nontrivial probe to unravel the character of the excitations of a
quantum spin liquid. In the S= 1/2 Kitaev model on the honeycomb lattice, Kondo impurities …

Spin–orbit coupling is a quantum effect that can give rise to exotic electronic and magnetic
states in the compounds of the 4d and 5d transition metals. Exploratory synthesis, chemical …

The quantum spin liquid is a highly entangled magnetic state characterized by the absence
of static magnetism in its ground state. Instead, the spins fluctuate in a highly correlated way …
