Magnetic monopoles—particles that behave as isolated north or south magnetic poles—have been the subject of speculation since the first detailed observations of magnetism several hundred years ago. Numerous theoretical investigations and hitherto unsuccessful experimental searches have followed Dirac’s 1931 development of a theory of monopoles consistent with both quantum mechanics and the gauge invariance of the electromagnetic field. The existence of even a single Dirac magnetic monopole… Expand
Observation of isolated monopoles in a quantum field
TLDR
An analog of the magnetic monopole has been created and observed in an ultracold gas of rubidium-87 atoms, and these observations lay the foundation for experimental studies of the dynamics and stability of topological point defects in quantum systems. Expand

Magnetic Monopoles and Dark Matter
Schwinger’s idea about the magnetic world of the early Universe, in which magnetic charges (monopoles) and magnetic atoms (g+g–) could be formed, is developed. In the present-day Universe magneticExpand

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.

Dirac Strings and Magnetic Monopoles in the Spin Ice Dy2Ti2O7
TLDR
Neutron scattering measurements on two spin-ice compounds show evidence for magnetic monopoles, and it is demonstrated the presence of such strings in the spin ice dysprosium titanate (Dy2Ti2O7). Expand
Synthetic magnetic fields for ultracold neutral atoms
TLDR
This work experimentally realizes an optically synthesized magnetic field for ultracold neutral atoms, which is evident from the appearance of vortices in the authors' Bose–Einstein condensate, and uses a spatially dependent optical coupling between internal states of the atoms, yielding a Berry’s phase sufficient to create large synthetic magnetic fields.

TLDR
This work studies this monopole in a Bose-Einstein condensate of degenerate dressed states and finds that the topological charge of the pseudospin cancels the monopole charge resulting in a vanishing gauge invariant charge. Expand
