Quantum Oscillation as Diagnostics of Pseudogap State in Underdoped Cuprates
Long Zhang, Jia-Wei Mei
The Fermi surface in underdoped cuprates is reconstructed by the charge density wave (CDW) order in the pseudogap phase. Theoretical proposals can be divided into two classes: one…

Reconstructed Fermi surface and quantum oscillation of doped resonating valence bond state with incommensurate charge order in underdoped cuprates
Long Zhang, Jia-Wei Mei
Recent experiments have revealed incommensurate charge density wave (CDW) in the pseudogap regime in underdoped cuprates, e.g. YBaCuO and HgBaCuO. Howev…

Sign Structure, Electron Fractionalization, and Emergent Gauge Description of the Hubbard Model
Long Zhang, Zheng-Yu Weng
The Fermi sign structure plays a crucial role for a Landau's Fermi liquid. In this work, we identify the exact sign structure for the bipartite Hubbard model at an arbitrary streng…
