The significance of Mendeleev's periodic table extends beyond the classification elements; it lies in its remarkable predictive power for discovering new elements and properties, revealing underlying symmetrical patterns nature that were only fully understood with advent quantum mechanics. Fundamental material such as electron transport magnetism, are also governed by crystal symmetry. In particular, spin depends on polarization electronic states, recently discovered materials where is independent momentum - a property known persistent texture (PST) promise extended lifetime efficient accumulation. this paper, we establish general conditions existence symmetry-protected PST bulk crystals. By systematically analyzing all 230 crystallographic space groups, similar to table, demonstrate universally present nonmagnetic solids lacking inversion Using group theory, identify regions within Brillouin zone host determine corresponding directions polarization. Our findings, supported first-principles calculations representative materials, open route robust spintronic based PST.
