BACKGROUND Years ago, Lev Landau taught us how to think about distinct phases of
matter through an order parameter that characterizes the symmetry-broken state relative to …

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 …

Machine learning (ML) has emerged as a formidable force for identifying hidden but
pertinent patterns within a given data set with the objective of subsequent generation of …

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 …

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 …

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 …

A quantum spin liquid is a state of matter where unpaired electrons' spins, although
entangled, do not show magnetic order even at the zero temperature. The realization of a …

We report on comprehensive results identifying the ground state of a triangular-lattice
structured YbZnGaO 4 as a spin glass, including no long-range magnetic order, prominent …

Triangular lattice of rare-earth ions with interacting effective spin-1/2 local moments is an
ideal platform to explore the physics of quantum spin liquids (QSLs) in the presence of …

A quantum spin liquid state has long been predicted to arise in spin-1/2 Heisenberg square-
lattice antiferromagnets at the boundary region between Néel (nearest-neighbor interaction …
