Rhombohedral Graphene: A Tale of Many Crystals
Ahmed Abouelkomsan, Filippo Gaggioli, Daniele Guerci +1
Experiments on rhombohedral graphene have uncovered an extraordinary wealth of correlated quantum phases - from chiral superconductors to electronic crystals - all within a single…
Attention-Based Foundation Model for Quantum States
Timothy Zaklama, Daniele Guerci, Liang Fu
We present an attention-based foundation model architecture for learning and predicting quantum states across Hamiltonian parameters, system sizes, and physical systems. Using only…
Anomalous Hall effect in rhombohedral graphene
Vera Mikheeva, Daniele Guerci, Daniel Kaplan +1
Motivated by recent experiments on rhombohedral stacked multilayer graphene and the observation of the anomalous Hall effect in a spontaneous spin-valley polarized quarter metal st…
Topological Kondo Insulator from Spin Loop Currents
Andreas Gleis, Kevin Lucht, Po-Jui Chen +3
We demonstrate that interacting electrons in AB-stacked realize a topological Kondo insulator at hole filling per moiré unit cell. In the p…
Topological superconductivity with emergent vortex lattice in twisted semiconductors
Daniele Guerci, Ahmed Abouelkomsan, Liang Fu
The coexistence of superconductivity and fractional quantum anomalous Hall (FQAH) effect has recently been observed in twisted MoTe and theoretically demonstrated in a model of…
Higher Chern bands in helical homotrilayer transition metal dichalcogenides
Jungho Daniel Choi, Nicolás Morales-Durán, Yves H. Kwan +3
We propose helically twisted homotrilayer transition metal dichalcogenides as a platform for realizing correlated topological phases of matter with higher and tunable Chern numbers…
