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 …

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 …

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 …

Motivated by experimental studies that have found signatures of a quantum spin liquid
phase in organic crystals whose structure is well described by the two-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 …

We propose an ab initio Boltzmann transport approach taking into account magnon-phonon
scattering (MPS) and three-phonon scattering simultaneously to accurately evaluate the …

States of matter with a sharp Fermi surface but no well-defined Landau quasiparticles arise
in a number of physical systems. Examples include (i) quantum critical points associated …

The density matrix renormalization group (DMRG) is one of the most powerful numerical
methods for studying two-dimensional quantum lattice systems, despite a perception that it is …

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 …
