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 …

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 …

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 …

Multiply periodic states appear in a wide variety of physical contexts, such as the Rayleigh–
Bénard convection, Faraday waves, liquid crystals and skyrmion crystals recently observed …

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 …

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 …

We propose a skyrmion-based universal quantum computer. Skyrmions have the helicity
degree of freedom in frustrated magnets, where twofold degenerated Bloch-type skyrmions …

A hallmark of the phase diagrams of quantum materials is the existence of multiple
electronic ordered states, which, in many cases, are not independent competing phases, but …

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 …

Ordering of the frustrated classical Heisenberg model on the triangular lattice with an
incommensurate spiral structure is studied under magnetic fields by means of a mean-field …
