Reconstructed Fermi surface and quantum oscillation of doped resonating valence bond state with incommensurate charge order in underdoped cuprates

Understand

Recent experiments have revealed incommensurate charge density wave (CDW) in the pseudogap regime in underdoped cuprates, e.g.

• YBa$_2$Cu$_3$O$_{6+\delta}$ and HgBa$_2$CuO$_{4+\delta}$.
• However, its relationship with the pseudogap is still controversial.
• In this work, we take a phenomenological synthesis of the doped resonating valence bond (RVB) state and the CDW order.
