Neutron scattering measurements of spin-ice materials contain signature pinch-point singularities, demonstrating the existence of an emergent electromagnetic gauge field. Here, the authors propose a system in which correlations manifest in pinch line

Spin systems on the frustrated kagome lattice exhibit classical and quantum spin liquids. Here, the authors present an anisotropic nearest-neighbour model with time-reversal symmetry which incorporates all known spin liquids, as well as promising chi

Frustration in magnetic interactions can give rise to disordered ground states with subtle and beautiful properties. The spin ices Ho_{2}Ti_{2}O_{7} and Dy_{2}Ti_{2}O_{7} exemplify this phenomenon, displaying a classical spin-liquid state, with fract

Spin ice is a paradigmatic frustrated system famous for the emergence of magnetic monopoles and a large magnetic entropy at low temperatures. It exhibits unusual behavior in the presence of an external magnetic field as a result of the competition be

There is a growing family of rare-earth kagome materials with dominant nearest-neighbor interactions and strong spin-orbit coupling. The low symmetry of these materials makes theoretical description complicated, with six distinct nearest-neighbor cou

Coulomb spin liquids are topological magnetic states obeying an emergent Gauss' law. Little distinction has been made between different kinds of Coulomb liquids. Here we show how a series of distinct Coulomb liquids can be generated straightforwardly

Exactly solvable models play a special role in Condensed Matter physics, serving as secure theoretical starting points for investigation of new phenomena. Changlani et al. [Phys. Rev. Lett. 120, 117202 (2018)] have discovered a limit of the XXZ model

In this chapter we introduce some analytical approaches which are useful for the description of quantum spin ice systems. Firstly, we will show how to obtain the dispersion relation of the emergent photons in the U(1) spin liquid phase of quantum spi

Dipolar-octupolar pyrochlore magnets in a strong external magnet field applied in the [110] direction are known to form a ``chain'' state, with subextensive degeneracy. Magnetic moments are correlated along one-dimensional chains carrying effective I

The pyrochlore material ${\mathrm{Nd}}_{2}{\mathrm{Zr}}_{2}{\mathrm{O}}_{7}$ with an ``all-in-all-out'' (AIAO) magnetic order shows novel quantum moment fragmentation with gapped flat dynamical spin ice modes. The parametrized spin Hamiltonian with a
