Non-Abelian and Abelian descendants of vortex spin liquid: fractional quantum spin Hall effect in twisted MoTe
Ya-Hui Zhang
The recent experimental observation of a potential fractional quantum spin Hall (FQSH) state in the twisted MoTe system has sparked theoretical explorations at total filling $ν…
Vortex spin liquid with fractional quantum spin Hall effect in moiré Chern bands
Ya-Hui Zhang
Integer and fractional quantum anomalous Hall (QAH) effects have been widely seen in moiré systems. Recently there is even observation of a time reversal invariant fractional quant…
S-wave pairing in a two-orbital t-J model on triangular lattice: possible application to PbCu(PO)O
Hanbit Oh, Ya-Hui Zhang
Recently room temperature superconductor was claimed in PbCu(PO)O (also known as LK-99) with . Density functional theory (DFT) calculations sug…
Ancilla wavefunctions of Mott insulator and pseudogap metal through quantum teleportation
Boran Zhou, Ya-Hui Zhang
Weak Mott regime with finite U is a wonderful region to search for quantum spin liquid, but it is challenging to write down a wavefunction capturing both spin liquid and charge flu…
Two-dimension to three-dimension transition of chiral spin liquid and fractional quantum Hall phases
Xiaofan Wu, Yahui Zhang
There have been lots of interest in two-dimensional (2D) fractional phases with an emergent U (1) gauge field. However, many experimental realizations are actually in three-dimensi…
Approximate SU(4) spin models on triangular and honeycomb lattices in twisted AB-Stacked WSe homo-bilayer
Shuchen Zhang, Boran Zhou, Ya-Hui Zhang
In this paper, we derive lattice models for the narrow moiré bands of the AB-stacked twisted WSe homobilayer through continuum model and Wannier orbital construction. Previous…
