TL;DR: This work proposes that magnetic monopoles emerge in a class of exotic magnets known collectively as spin ice: the dipole moment of the underlying electronic degrees of freedom fractionalises into monopoles, which would account for a mysterious phase transition observed experimentally in spin ice in a magnetic field.

TL;DR: The excitation spectrum of α-RuCl3 is proposed as a prime candidate for fractionalized Kitaev physics, and dynamical response measurements above interlayer energy scales are naturally accounted for in terms of deconfinement physics expected for QSLs.

TL;DR: It is shown that their disordered Floquet many-body localized counterparts can exhibit distinct ordered phases delineated by sharp transitions, and these are analogs of equilibrium states with broken symmetries and topological order.

TL;DR: The quantum dimer model on the triangular lattice is studied, which is expected to describe the singlet dynamics of frustrated Heisenberg models in phases where valence bond configurations dominate their physics, and it is found that there is a truly short ranged resonating valence Bond phase with no gapless excitations and with deconfined, gapped, spinons for a finite range of parameters.

TL;DR: In this paper, the authors provide experimental evidence that a material based on ruthenium, δ-RuCl$_3$ realizes the same Kitaev physics but is highly amenable to neutron investigation, and show that stacking faults, inherent to the highly 2D nature of the material, readily explain some puzzling results.
