Neutron scattering under ~0.6% tensile strain reveals C2 symmetry in spin excitations of FePSe3 that persists above TN, indicating three-state Potts nematicity from vestigial zigzag AFM order.
A formalism for nemato-elasticity enforces Saint Venant compatibility via a helical basis, yielding direction-selective criticality and defect-induced random fields as universal features of crystalline systems.
Elastic compatibility constraints bifurcate nematic fluctuations into critical compatible and gapped incompatible sectors, yielding universal direction-selective nematic criticality protected from microscopic defect strains.
