Valley-Helical Superconductivity Driven by Repulsion and Quantum Geometry: Applications to Time-Reversal Symmetric Rhombohedral Graphene
Julian May-Mann, Trithep Devakul, Gal Shavit
Motivated by the recent experimental signatures of chiral superconductivity in valley-polarized graphene- and transition-metal-dichalcogenide-based systems, we investigate the poss…
Fractional Chern mosaic in supermoiré graphene
Yves H. Kwan, Tixuan Tan, Trithep Devakul
We propose the realization of a fractional Chern mosaic: a state characterized by a spatially varying topological order. This state is enabled by a separation of length scales that…

Nicole Sabina Ticea, Julian May-Mann, Jiewen Xiao +2
We study the effects of quasiperiodicity on the stability of conventional and unconventional superconductors. Quasiperiodicity is modelled using the three-dimensional Aubry-Andre m…

Tixuan Tan, Aidan P. Reddy, Liang Fu +1
We show that topological flat minibands can be engineered in a class of narrow gap semiconductor films using only an external electrostatic superlattice potential. We demonstrate t…
Multi-moiré trilayer graphene: lattice relaxation, electronic structure, and magic angles
Charles Yang, Julian May-Mann, Ziyan Zhu +1
We systematically explore the structural and electronic properties of twisted trilayer graphene systems. In general, these systems are characterized by two twist angles, which lead…

Moiré engineering in atomically thin van der Waals heterostructures creates artificial quantum materials with designer properties. We solve the many-body problem of interacting ele…

We study 't Hooft anomalies and the related anomaly inflow for subsystem global symmetries. These symmetries and anomalies arise in a number of exotic systems, including models wit…
Quantum anomalous Hall effect from inverted charge transfer gap
Trithep Devakul, Liang Fu
A general mechanism is presented by which topological physics arises in strongly correlated systems without flat bands. Starting from a charge transfer insulator, topology emerges…

Yang Zhang, Trithep Devakul, Liang Fu
While transition metal dichalcogenide (TMD) based moire materials have been shown to host various correlated electronic phenomena, topological states have not been experimentally o…
