Charge order-driven nematicity in the nickel-pnictide superconductor Ba $_{1 - x}$ Sr $_{x}$ Ni $_{2}$ As $_{2}$

Thomas Johnson, Camille Bernal-Choban, Sangjun Lee +8

Nematic order refers to the spontaneous breaking of rotational symmetry while preserving translational symmetry. First identified in classical liquid crystals, nematic order arises…
