Anti-topological crystal and non-Abelian liquid in twisted semiconductor bilayers
Aidan P. Reddy, D. N. Sheng, Ahmed Abouelkomsan +2
We show that electron crystals compete closely with non-Abelian fractional Chern insulators in the half-filled second moiré band of twisted bilayer MoTe. Depending on the twist…
Tuning competition between charge order and superconductivity in the square-lattice -- model
Xin Lu, Huaiming Guo, Wei-Qiang Chen +2
Recently, a flurry of works have found strong competition between charge density wave (CDW) and superconductivity (SC) in the doped Hubbard and - models on the square lattice…
Robust non-Abelian even-denominator fractional Chern insulator in twisted bilayer MoTe
Feng Chen, Wei-Wei Luo, Wei Zhu +1
A recent experiment observes a series of quantum spin Hall effects in transition metal dichalcogenide moiré MoTe [K. Kang, et. al, Nature 628, 522-526 (2024)]. Among them, the…
Quantum anomalous Hall crystal at fractional filling of moiré superlattices
D. N. Sheng, Aidan P. Reddy, Ahmed Abouelkomsan +2
We predict the emergence a state of matter with intertwined ferromagnetism, charge order and topology in fractionally filled moiré superlattice bands. Remarkably, these quantum ano…
Quantum Melting of Generalized Wigner Crystals in Transition Metal Dichalcogenide Moiré Systems
Yiqing Zhou, D. N. Sheng, Eun-Ah Kim
Generalized Wigner Crystal (GWC) is a novel quantum phase of matter driven by further-range interaction at fractional fillings of a lattice. The role of further range interaction a…
Chiral spin liquid and quantum phase diagram of spin- -- model on the square lattice
Xiao-Tian Zhang, Yixuan Huang, Han-Qing Wu +2
We study the spin- Heisenberg model on the square lattice with the first and second nearest-neighbor antiferromagnetic couplings , , as well as the three-spin scalar…
