Visualizing the Energy-gap Modulations of the Cuprate Pair Density Wave State
Zengyi Du, Hui Li, Sanghyun Joo +6
When Cooper pairs are formed with finite center-of-mass momentum, the defining characteristic is a spatially modulating superconducting energy gap . Recently, this concept ha…
Homogeneous superconducting gap in DBCO synthesized by oxide molecular beam epitaxy
Ze-Bin Wu, Daniel Putzky, Asish K. Kundu +12
Much of what is known about high-temperature cuprate superconductors stems from studies based on two surface analytical tools, angle-resolved photoemission spectroscopy (ARPES) and…
Atomic-scale Electronic Structure of the Cuprate Pair Density Wave State Coexisting with Superconductivity
Peayush Choubey, Sang Hyun Joo, K. Fujita +9
The defining characteristic of hole-doped cuprates is -wave high temperature superconductivity. However, intense theoretical interest is now focused on whether a pair density wa…
Detection of a Cooper-Pair Density Wave in BiSrCaCuO
M. H. Hamidian, S. D. Edkins, Sang Hyun Joo +9
The quantum condensate of Cooper-pairs forming a superconductor was originally conceived to be translationally invariant. In theory, however, pairs can exist with finite momentum $…
