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

The defining problem in frustrated quantum magnetism, the ground state of the nearest-
neighbor S= 1/2 antiferromagnetic Heisenberg model on the kagome lattice, has defied all …

Frustrated magnets are materials in which localized magnetic moments, or spins, interact
through competing exchange interactions that cannot be simultaneously satisfied, giving rise …

In metals, electrons in a magnetic field undergo cyclotron motion, leading to oscillations in
physical properties called quantum oscillations. This phenomenon has never been seen in a …

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 …

Quantum spin liquids form a novel class of matter where, despite the existence of strong
exchange interactions, spins do not order down to the lowest measured temperature …

We review the interplay of frustration and strong electronic correlations in quasi-two-
dimensional organic charge transfer salts, such as (BEDT-TTF) 2 X and Et n Me 4− n Pn [Pd …

The frustration of antiferromagnetic interactions on the loosely connected kagome lattice
associated to the enhancement of quantum fluctuations for S= 1/2 spins was acknowledged …

The discovery of magnetism by the ancient Greeks was enabled by the natural occurrence of
lodestone–a magnetized version of the mineral magnetite. Nowadays, natural minerals …
