Abstract

Arising from: Kaminski, A. et al. Nature 416, 610–613 (2002); Kaminaski et al. reply One of the mysteries of modern condensed-matter physics is the nature of the pseudogap state of the superconducting cuprates. Kaminski et al.1 claim to have observed signatures of time-reversal symmetry breaking in the pseudogap regime in underdoped Bi2Sr2CaCu2O8+δ (Bi2212). Here we argue that the observed circular dichroism is due to the 5×1 superstructure replica of the electronic bands and therefore cannot be considered as evidence for spontaneous time-reversal symmetry breaking in cuprates.
