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. Spec…

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…
