Superconductivity of highly spin-polarized electrons in FeSe probed by NMR Open
A number of recent experiments indicate that the iron-chalcogenide FeSe\nprovides the long-sought possibility to study bulk superconductivity in the\ncross-over regime between the weakly coupled Bardeen--Cooper--Schrieffer (BCS)\npairing a…

Splitting of the magnetic monopole pair-creation energy in spin ice Open
The thermodynamics in spin-ice systems are governed by emergent magnetic monopole excitations and, until now, the creation of a pair of these topological defects was associated with one specific pair-creation energy. Here, we show that the…
