Nematicity with a twist: rotational symmetry breaking in a moiré superlattice
Rafael M. Fernandes, Jörn W. F. Venderbos
Motivated by recent reports of nematic order in twisted bilayer graphene (TBG), we investigate the impact of the triangular moiré superlattice degrees of freedom on nematicity. In…

Observation of three-state nematicity in the triangular lattice antiferromagnet Fe NbS
Arielle Little, Changmin Lee, Caolan John +9
Nematic order is the breaking of rotational symmetry in the presence of translational invariance. While originally defined in the context of liquid crystals, the concept of nematic…
