Abstract: At low temperatures, spin ice is populated by a finite density of magnetic monopoles-pointlike topological defects with a mutual magnetic Coulomb interaction. We discuss the properties of th...

We consider spin ice magnets (primarily, Dy2Ti2O7) in the vicinity of their critical point on the (H, T )plane. We find that the longitudinal susceptibility diverges at the critical point, leading to ...

While sources of magnetic fields — magnetic monopoles — have so far proven elusive as
elementary particles, several scenarios have been proposed recently in condensed matter physics
of emergent quas...
