Translational symmetry breaking in the electronic nematic phase of BaFe2As2

K. Koshiishi, L. Liu, K. Okazaki +13

The microscopic origin of the nematicity, namely, four-fold rotational symmetry breaking in iron-based superconductors has been controversial since its discovery. In particular, it…

Smectic Pair Density Wave Order in EuRbFe4As4

He Zhao, Raymond Blackwell, Morgan Thinel +7

The pair density wave (PDW) is a novel superconducting state in which Cooper pairs carry center-of-mass momentum in equilibrium, leading to the breaking of translational symmetry.…
