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…

Unveiling Stripe-shaped Charge Density Modulations in Doped Mott Insulators
Ning Xia, Yuchen Guo, Shuo Yang
Inspired by recent experimental findings, we investigate various scenarios of the doped Hubbard model with impurity potentials. We calculate the lattice Green's function in a finit…
