Extended symmetric quantum phase in a honeycomb Heisenberg model with sublattice-selective interactions
Nai Chao Hu, Xing-Yu Zhang, Yuchi He +1
Motivated by two-dimensional bilayer systems we numerically study an anti-ferromagnetic spin- Heisenberg model on the honeycomb lattice with a nearest-neighbour exchange coupl…
Velocity collapse and non-conformal spiral phase in the sawtooth spin chain
Nai Chao Hu
Recent matrix-product-state calculations show that the spiral phase in the sawtooth chain has numerical signatures that are difficult to reconcile with an ordinary conformal critic…
Multi-Q spin-valley order in twisted WSe2
Arthur Bril, Nai Chao Hu, Nick Bultinck
We report on a study of the interacting phase diagram of -twisted WSe at moiré hole filling , in which we find previously-overlooked types of magnetism. Specif…
Valence-bonds, spin liquids and unconventional criticality in a 1D Kondo insulator
Nai Chao Hu, Rui-Zhen Huang, Nick Bultinck
We consider a one-dimensional multi-orbital Kondo lattice model and show that by tuning the kinetic energy of the itinerant electrons it is possible to stabilize Kondo insulators w…
Itinerant ferromagnetism in transition metal dichalcogenides moiré superlattices
Pawel Potasz, Nicolás Morales-Durán, Nai Chao Hu +1
Moiré materials are artificial crystals formed at van der Waals heterojunctions that have emerged as a highly tunable platform to realize much of the rich quantum physics of electr…
Giant spin Hall effect in AB-stacked MoTe2/WSe2 bilayers
Zui Tao, Bowen Shen, Wenjin Zhao +9
The spin Hall effect (SHE), in which electrical current generates transverse spin current, plays an important role in spintronics for the generation and manipulation of spin-polari…
Gate-tunable heavy fermion quantum criticality in a moiré Kondo lattice
Ajesh Kumar, Nai Chao Hu, Allan H. MacDonald +1
We propose a realization of Kondo-lattice physics in moiré superlattices at the interface between a WX homobilayer and MoX monolayer (where X=S,Se). Under appropriate gatin…
Competing magnetic states in transition metal dichalcogenide moiré materials
Nai Chao Hu, Allan H. MacDonald
Small-twist-angle transition metal dichalcogenide (TMD) heterobilayers develop isolated flat moiré bands that are approximately described by triangular lattice generalized Hubbard…
Non-local interactions in moiré Hubbard systems
Nicolás Morales-Durán, Nai Chao Hu, Pawel Potasz +1
Moiré materials formed in two-dimensional semiconductor heterobilayers are quantum simulators of Hubbard-like physics with unprecedented electron-density and interaction-strength t…
