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 are an exciting playground for exotic physical phenomena and
emergent many-body quantum states. The realization and discovery of quantum spin liquid …

The honeycomb lattice is one of the simplest lattice structures. Electrons and spins on this
simple lattice, however, often form exotic phases with non-trivial excitations. Massless Dirac …

For decades, frustrated quantum magnets have been a seed for scientific progress and
innovation in condensed matter. As much as the numerical tools for low-dimensional …

The discovery of magnetism by the ancient Greeks was enabled by the natural occurrence of
lodestone–a magnetized version of the mineral magnetite. Nowadays, natural minerals …

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 …

The search for the experimental evidence of quantum spin liquid (QSL) states is critical but
extremely challenging, as the quenched interaction randomness introduced by structural …

Quantum fluctuations enhanced by frustration and subtle interplay between competing
degrees of freedom offer an ideal ground to realize novel states with fractional quantum …

Here we report the observation of pressure-induced melting of antiferromagnetic (AFM)
order and the emergence of a new state in the honeycomb-lattice halide α-RuC l 3, a …

The interplay between competing degrees of freedom can stabilize nontrivial magnetic
states in correlated electron materials. Frustration-induced strong quantum fluctuations can …
