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 …

The Heisenberg triangular-lattice quantum spin liquid and its phase transitions to nearby
magnetic orders have received much theoretical attention, but clear experimental …

A quantum spin liquid is an exotic quantum state of matter in which spins are highly
entangled and remain disordered down to zero temperature. Such a state of matter is …

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 …

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 …

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 …
