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…
Global phase diagram of doped quantum spin liquid on the Kagome lattice
Zheng-Tao Xu, Zheng-Cheng Gu, Shuo Yang
It has long been believed that doped quantum spin liquids (QSLs) can give rise to fascinating quantum phases, including the possibility of high-temperature superconductivity (SC) a…
