Scattering interference signature of a pair density wave state in the cuprate pseudogap phase
An unidentified quantum fluid designated the pseudogap (PG) phase is produced by electron-density depletion in the CuO(2) antiferromagnetic insulator. Current theories suggest that the PG phase may be a pair density wave (PDW) state characterized by a spatially modulating density of electron pairs....

description | An unidentified quantum fluid designated the pseudogap (PG) phase is produced by electron-density depletion in the CuO(2) antiferromagnetic insulator. Current theories suggest that the PG phase may be a pair density wave (PDW) state characterized by a spatially modulating density of electron pairs. Such a state should exhibit a periodically modulating energy gap [Formula: see text] in real-space, and a characteristic quasiparticle scattering interference (QPI) signature [Formula: see text] in wavevector space. By studying strongly underdoped Bi(2)Sr(2)CaDyCu(2)O(8) at hole-density ~0.08 in the superconductive phase, we detect the 8a(0)-periodic [Formula: see text] modulations signifying a PDW coexisting with superconductivity. Then, by visualizing the temperature dependence of this electronic structure from the superconducting into the pseudogap phase, we find the evolution of the scattering interference signature [Formula: see text] that is predicted specifically for the temperature dependence of an 8a(0)-periodic PDW. These observations are consistent with theory for the transition from a PDW state coexisting with d-wave superconductivity to a pure PDW state in the Bi(2)Sr(2)CaDyCu(2)O(8) pseudogap phase. |
