Color map depicting how the new helical basis parameter Φ1 is related to the old, d-orbital basis for different directions of momentum q. The map shows ‘how much’ each of the five d-orbital basis vectors (each denoted by one of five colors) contributes to Φ1 in different momentum directions. This particular mode quantifies the local expansion or compression of the lattice needed to prevent cracking. Similar color maps exist for the remaining helical basis parameters Φ2, Φ3, Φ4, and Φ5 but are not shown here. (Credit: W.J. Meese, R.M. Fernandes, Phys. Rev. Lett. 136, 166501, Apr. 20th, 2026)
