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…
Atomic-Scale Visualization of the Cuprate Pair Density Wave State
Zengyi Du, Hui Li, Kazuhiro Fujita
A recent discovery of the pair density wave (PDW) order creates a stir in understanding an underlying physics in the pseudogap states of the cuprate high temperature superconductor…
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…
Direct visualization of sign reversal s^+- superconducting gaps in FeTe0.55Se0.45
Mingyang Chen, Qingkun Tang, Xiaoyu Chen +7
In many unconventional superconductors, the pairing of electrons is driven by the repulsive interaction, which leads to the sign reversal of superconducting gaps along the Fermi su…
Directly visualizing the sign change of d-wave superconducting gap in Bi2Sr2CaCu2O8+δ by phase-referenced quasiparticle interference
Qiangqiang Gu, Siyuan Wan, Qingkun Tang +7
The superconducting state is achieved by the condensation of Cooper pairs and is protected by the superconducting gap. The pairing interaction between the two electrons of a Cooper…
Direct Evidence of Superconductivity with Twofold Symmetry in Bi2Te3 Thin Film Deposited on FeTe0.55Se0.45
Minyang Chen Xiaoyu Chen, Huan Yang, Zengyi Du +1
Topological superconductor is a timely and frontier topic in condensed matter physics. In superconducting state, an order parameter will be established with the basic or subsidiary…
