Extended Data Fig. 6: Comparing measurements of angle dependent magnetoresistivity to expectations for a bi-axial charge-density-wave reconstruction.
From: Observation of the Yamaji effect in a cuprate superconductor
a, Magnetoresistivity δρc as a function θ for ϕ = 0∘, 23∘ and 45∘. b, Simulations for a reconstructed Fermi surface resulting from bi-axial charge-density-wave previously studied at low temperatures (T ≲ 4 K)12,39,40 This pocket has four-fold planar symmetry in agreement with the symmetry of the measured linear slope of magnetoresistivity a1(ϕ) for in-plane fields, but it cannot capture the observed evolution of the Yamaji effect shown in panel a. c & d, Simulations for slight variations of the curvature of the reconstructed CDW pocket, while keeping the enclosed area of the pocket the same. The insets shows a closeup of the reconstructed pocket (reproduced from panel b inset) in blue and the modified pocket in red. Experimentally, the Yamaji peak for ϕ = 0∘ is more pronounced than that for ϕ = 45∘. The opposite is always found for simulations of the CDW pocket.
