Nematicity

Nematicity is an electronically driven breaking of rotational symmetry giving rise to anisotropic electronic properties. Iron based superconductors FeSe and BaFe2_2As2_2 are two examples of nematic metals that happen to both host unconventional superconductivty. In many instances, nematicity comes hand in hand with some variety of mangetism. Perhaps uniquely, FeSe host nematicity in the absence of static magnetism. Magnetism can be stabilized with the application of pressure allowing for their respective roles with regard to superconductivity to be distangled.
