Abstract

Pseudogap versus superconductivity in cuprates A pairing gap and coherence are the two hallmarks of superconductivity. In a classical BCS (Bardeen–Cooper–Schreiffer) superconductor they are established simultaneously at the critical temperature, Tc. In the cuprates however, an energy gap (pseudogap) extends above Tc. The origin of this gap is one of the central issues in high-temperature superconductivity. Kondo et al. report evidence from angle-resolved photoemission spectroscopy (ARPES) that the pseudogap and high-temperature superconductivity represent two competing orders, with the pseudogap competing with the superconductivity by depleting the spectral weight available for pairing.
