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 …

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 …

Abstract Antiferromagnetically coupled S= 1/2 spins on an isotropic triangular lattice are the
paradigm of frustrated quantum magnetism, but structurally ideal realizations are rare. Here …

We analyze the effect of quenched disorder on spin-1/2 quantum magnets in which
magnetic frustration promotes the formation of local singlets. Our results include a theory for …

We suggest that a randomization of the pseudodipolar interaction in the spin-orbit-generated
low-energy Hamiltonian of YbMgGaO 4 due to an inhomogeneous charge environment from …

Frustration in magnetic materials arising from competing exchange interactions can prevent
the system from adopting long-range magnetic order and can instead lead to a diverse …

Frustrated quantum magnets are expected to host many exotic quantum spin states like
quantum spin liquid (QSL), and have attracted numerous interest in modern condensed …

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 …

High-quality single crystals of NaYbSe 2, which resembles a perfect triangular-lattice
antiferromagnet without intrinsic disorder, are investigated by magnetization and specific …

We apply moderate-high-energy inelastic neutron scattering (INS) measurements to
investigate Yb 3+ crystalline electric field (CEF) levels in the triangular spin-liquid candidate …
