Density wave order with antiphase feature associated with the pseudogap in cuprate superconductor Bi2+xSr2-xCuO6+delta
Zhaohui Wang, Han Li, Shengtai Fan +3
The strong correlation effect in cuprate superconductors have greatly enriched the phase diagram showing the co-existence of superconductivity with many intertwined orders. One of…
Helical edge states and enhanced superconducting gaps in Bi islands on FeTeSe
Chuanhao Wen, Zhiyong Hou, Zhiyuan Shang +2
By measuring scanning tunneling spectroscopy on some large Bi islands deposited on FeTeSe superconductors, we observe clear evidence of topological in-gap edge st…
"Half-Bogoliubons" as the intermediate states for the phase coherence in underdoped cuprates
Han Li, Zhaohui Wang, Shengtai Fan +3
Superconductivity is achieved by the pairing of electrons and phase coherence between the Cooper pairs. According to the Bardeen-Cooper-Schrieffer theory, the quasiparticles with B…
Unprecedentedly large gap in HgBaCaCuO with the highest at ambient pressure
Chuanhao Wen, Zhiyong Hou, Alireza Akbari +6
In cuprate superconductors, the highest is possessed by the HgBaCaCuO (Hg-1223) system at ambient pressure, but the reason remains elusive. Here we repor…
Preformed Cooper Pairs in a Triclinic Iron Pnictide Superconductor
Zezhong Li, Wenshan Hong, Honglin Zhou +10
Electron pairing along with phase coherence generates superconductivity below the critical temperature (). In underdoped high- cuprates, these two quantum phenomena may o…
Growth and characterization of the LaNiO thin films: dominant contribution of the orbital at ambient pressure
Yuecong Liu, Mengjun Ou, Haifeng Chu +4
By using the pulsed-laser-ablation technique, we have successfully grown the LaNiO thin films with -axis orientation perpendicular to the film surface. X-ra…
