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 …

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 …

We investigate the spin-1 2 Heisenberg model on the triangular lattice in the presence of
nearest-neighbor J 1 and next-nearest-neighbor J 2 antiferromagnetic couplings. Motivated …

A peculiar feature of quantum states is that they may embody so-called projective
representations of symmetries rather than ordinary representations. Projective …

For the classification of topological phases of matter, an important consideration is whether a
system is spinless or spinful, as these two classes have distinct symmetry algebra that gives …

A promising route towards the realization of chiral spin liquids is the quantum melting of
classically noncoplanar spin states via quantum fluctuations. In the classical realm, such …

We investigate the J 1-J 2 Heisenberg model on the triangular lattice with an additional
scalar chirality term and show that a chiral spin liquid is stabilized in a sizable region of the …

We investigate the nature of the ground state of the spin-1 2 Heisenberg antiferromagnet on
the shuriken lattice by complementary state-of-the-art numerical techniques, such as …

We study the spin-1/2 Heisenberg model on the triangular lattice with the nearest-neighbor J
1> 0, the next-nearest-neighobr J 2> 0 Heisenberg interactions, and the additional scalar …

Pinch point singularities, associated with flat band magnetic excitations, are tell-tale
signatures of Coulomb spin liquids. While their properties in the presence of quantum …
