First-principles study of an organometallic S=1/2 kagome compound
Zheng Liu, Jia-Wei Mei, Feng Liu
Cu(1,3-benzenedicarboxylate) [Cu(1,3-bdc)] contains structurally perfect kagomé planes formed by Cu ions without the presence of diamagnetic defects. This organometallic com…
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…
Modular matrices from universal wave function overlaps in Gutzwiller-projected parton wave functions
Jia-Wei Mei, Xiao-Gang Wen
We implement the universal wave function overlap (UWFO) method to extract modular and matrices for topological orders in Gutzwiller-projected parton wave functions (GPWFs).…
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…
Symmetry Protected Topological Order in Gutzwiller Wave Functions
Zheng-Xin Liu, Jia-Wei Mei, Peng Ye +1
Gutzwiller projection is a way to construct many-body wave functions that could carry topological order or symmetry protected topological (SPT) order. However, an important issue i…
Design local spin models for Gutzwiller-projected parton wave functions
Jia-Wei Mei, Xiao-Gang Wen
We introduce a method to design a local spin Hamiltonian to realize a Gutzwiller-projected parton wave functions (GPWF) as its ground state. For example, the Dirac spin liquid (DSL…
