Magnetic Monopoles Magnets come with a north and a south pole. Despite being predicted to exist, searches in astronomy and in high-energy particle physics experiments for magnetic monopoles (either north or south on their own) have defied observation. Theoretical work in condensed-matter systems has predicted that spin-ice structures may harbor such elusive particles (see the Perspective by Gingras). Fennell et al. (p. 415, published online 3 September) and Morris et al. (p. 411, published… Expand
Observation of Dirac monopoles in a synthetic magnetic field
TLDR
These real-space images provide conclusive and long-awaited experimental evidence of the existence of Dirac monopoles, and provides an unprecedented opportunity to observe and manipulate these quantum mechanical entities in a controlled environment. Expand
Observing Monopoles in a Magnetic Analog of Ice
TLDR
Measurements from neutron-scattering experiments showing that the low-energy excitations in spin ices are reminiscent of Dirac's elementary magnetic monopoles that have so far eluded the searches of high-energy physicists are reported. Expand
Evidence for the confinement of magnetic monopoles in quantum spin ice.
TLDR
The detection of a hierarchy of unequally-spaced magnetic excitations via high resolution inelastic neutron spectroscopic measurements on the quantum spin ice candidate is reported. Expand
Magnetic monopole noise
TLDR
Almost all of the features of magnetic-flux noise predicted for magnetic monopole plasmas are detected, including the existence of intense magnetization noise and its characteristic frequency and temperature dependence. Expand

TLDR
It is shown that phonons or lattice shear strain generate topological monopoles in some low-dimensional quantum antiferromagnets, based on mapping the spin degrees of freedom onto spinless fermions using the generalized Jordan–Wigner transformation in dimensions higher than one. Expand
Emergent magnetic monopoles, disorder, and avalanches in artificial kagome spin ice (invited)

Higgs transition from a magnetic Coulomb liquid to a ferromagnet in Yb2Ti2O7
TLDR
Evidence of a Higgs transition from a magnetic Coulomb liquid to a ferromagnet in single-crystal Yb2Ti2O7 is reported, which is explained on the basis of a quantum spin-ice model, whose high-temperature phase is effectively described as a magnetism liquid, whereas the ground state shows a nearly collinear ferromaggnetism with gapped spin excitations.

Magnetic monopoles in spin ice
TLDR
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.

Monopole and Dirac string Dynamics in Spin Ice
Magnetic monopoles have eluded experimental detection since their prediction nearly a century ago by Dirac. Recently it has been shown that classical analogues of these enigmatic particles occur asExpand

How ‘spin ice’ freezes
TLDR
A cooperative spin-freezing transition leading to the spin-ice ground state in Dy2Ti2O7, a site-ordered magnetic material in which the spins reside on a lattice of corner-sharing tetrahedra where they form an unusual magnetic ground state known as ‘spin ice’ is identified. Expand
Dipolar spin correlations in classical pyrochlore magnets.
TLDR
It is conjecture that a local constraint obeyed by the extensively degenerate ground states dictates a dipolar form for the asymptotic spin correlations, at all N not equal 2 for which the system is paramagnetic down to T=0. Expand
