Vestigial nematicity from spin and/or charge order in the cuprates
Vestigial nematicity from spin and/or charge order in the cuprates
Nematic order has manifested itself in a variety of materials in the cuprate family. We propose an effective field theory of a layered system with incommensurate, intertwined spin- and charge-density wave (SDW and CDW) orders, each of which consists of two components related by ${C}_{4}$ rotations. Using a variational method …
