From: Broken rotational symmetry on the Fermi surface of a high-Tc superconductor
Simulated magnetoresistance from a single bilayer-split pocket inYBa2Cu3O6.58. The model Fermi surface consists of three dominant breakdown sections (a) that combine the in-plane diamond geometry of Fig. 3 with the interlayer dispersion symmetries of Fig. 2b (which were shown with isotropic k F to emphasize their symmetry). The raw magnetoresistivity data is reproduced in panel b, truncated at θ = 58° at the onset of superconductivity. Panel c is a simulation of this data using the three magnetic breakdown orbits contributing to the dominant QO frequency, which have symmetries shown in Fig. 2b. The strongest contribution comes from the cylinder with sinϕ cosk z warping, which explains the dominant C2 symmetry we observe in the AMR
