Effect of symmetry distortions on photoelectron selection rules and spectra of Bi₂Sr₂CaCu₂O8+ delta

الأصل · EN

We derive photoelectron selection rules along the glide plane in orthorhombic Bi₂Sr₂CaCu₂O₈₊δ (Bi2212). These selection rules explain the reversed intensity behavior of the shadow and the main band of the material as a natural consequence of the variating representation of the final state as a function of k∥. Our one-step simulations strongly support the structural origin of the shadow band but we also introduce a scenario for detecting antiferromagnetic signatures in low doping.
