We review the recent advances and current challenges in the field of strong spin-orbit
coupled Kitaev materials, with a particular emphasis on the physics beyond the exactly …

Quantum spin liquids may be considered'quantum disordered'ground states of spin systems,
in which zero-point fluctuations are so strong that they prevent conventional magnetic long …

A quantum spin liquid (QSL) is an exotic state of matter in which electrons' spins are
quantum entangled over long distances, but do not show magnetic order in the zero …

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 …

We describe recent progress in our understanding of the interplay between interactions,
symmetry, and topology in states of quantum matter. We focus on a minimal generalization …

The spin ice materials, including Ho 2 Ti 2 O 7 and Dy 2 Ti 2 O 7, are rare-earth pyrochlore
magnets which, at low temperatures, enter a constrained paramagnetic state with an …

In this review, we provide an introduction to the physics of a series of frustrated quantum rare-
earth pyrochlores. We first give a background on the microscopic single-and two-ion physics …

YbMgGaO 4, a structurally perfect two-dimensional triangular lattice with an odd number of
electrons per unit cell and spin-orbit entangled effective spin-1/2 local moments for the Yb …

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 …
