Chern-Selective multi-valley Flat Bands in Twisted Mono-Bilayer and Mono-Trilayer MoTe
Ziyue Qi, Hanqi Pi, Yan Zhang +6
The interplay between moiré flat bands originating from different valleys can give rise to a variety of exotic quantum phases. In this work, we investigate the electronic properti…
Engineering topological flat bands in -valley moiré systems with Ising-type SOC: twisted 1T-ZrS and 1T-SnSe
Hanqi Pi, Yves H. Kwan, Haoyu Hu +8
Twisted moiré superlattices hosting topological flat bands provide a platform to explore the interplay between topology and correlations. Here we investigate topological band stru…
Emergent Interacting Phases in the Strong Coupling Limit of Twisted M-Valley Moiré Systems: Application to SnSe
Ming-Rui Li, Dumitru Calugaru, Yi Jiang +10
We construct an interacting Wannier model for both AA-stacked and AB-stacked twisted SnSe2, revealing a rich landscape of correlated quantum phases. For the AA-stacked case, the sy…
2D Theoretically Twistable Material Database
Yi Jiang, Urko Petralanda, Grigorii Skorupskii +22
The study of twisted two-dimensional (2D) materials, where twisting layers create moiré superlattices, has opened new opportunities for investigating topological phases and strong…
A New Moiré Platform Based on M-Point Twisting
Dumitru CÄlugÄru, Yi Jiang, Haoyu Hu +9
We introduce a new class of moiré systems and materials based on monolayers with triangular lattices and low-energy states at the M points of the Brillouin zone. These M-point moi…
Quantum geometry and critical temperature enhancement in MgB superconductivity
Yi Jiang, Haoyu Hu, Dumitru CÄlugÄru +13
MgB, a phonon-mediated superconductor with record-high critical temperature K, is revisited to obtain a comprehensive theory of electrons, phonons, and their cou…
