Quantum interference effects can, in theory, lead to the emergence of new particles carrying exotic quantum numbers at a critical point. But how good is the evidence that this happens?

The band structure of iron-based superconductors gives rise to yet another scenario for the appearance of Dirac fermions.

With a clever design of a ferromagnetic Josephson junction, it is possible to observe a theoretically predicted, but difficult to measure, spin-triplet supercurrent.

Unconventional superconductors in the proximity of a topological insulator exhibit zero-energy Majorana surface states.

A theory of novel phase formation near quantum critical points suggests that large fluctuations lead to magnetic analogs of inhomogeneous superconductivity.

Density-functional calculations provide a comprehensive picture of how magnetic order evolves with doping in two iron pnictide compounds.
