Eight-unit-cell electronic modulations in cuprates originating from local molecular orbitals
Zhiheng Yao, Sixuan Chen, Jianfa Zhao +10
The pair density wave (PDW) state with eight-unit-cell (8a0) periodicity has been widely regarded as the primary order in cuprates, yet its existence and origin remain subjects of…
Half-filled metal and molecular-orbital-mediated pairing in cuprate
Sixuan Chen, Zhiheng Yao, Ning Xia +7
The cuprates exhibit anomalous momentum-space structure with antinodal gap and nodal arc in the underdoped regime, which evolves into a complete hole-type Fermi surface with a larg…
Time-reversal symmetry-breaking phenomena in transport study of kagome superconductivity
Shuo-Ying Yang, Jia-Xin Yin
Recent studies have found that all three materials within the vanadium-based kagome superconductors (VSb, = K, Cs, Rb) exhibit time-reversal sy…
Pseudogap phase as fluctuating pair density wave
Zheng-Yuan Yue, Zheng-Tao Xu, Shuo Yang +1
The physical nature of pseudogap phase is one of the most important and intriguing problems towards understanding the key mechanism of high temperature superconductivity in cuprate…
