Four-moment criteria for Poisson convergence on Poisson and Rademacher chaoses
Guangqu Zheng
In this paper, we establish Poisson limit theorems on Poisson and Rademacher chaoses. Our principal result is a total-variation bound, valid in both settings, for an integer-valued…
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…
Magnetic Signatures of a Putative Fractional Topological Insulator in Twisted MoTe2
Yiping Wang, Gillian E. Minarik, Weijie Li +15
The interplay among electronic correlation, topology, and time-reversal-symmetry (TRS) often leads to exotic quantum states of matter, as highlighted by the discoveries of fraction…
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…
Does Moire Matter? Critical Moire Dependence with Quantum Fluctuations in Graphene Based Integer and Fractional Chern Insulators
Zihao Huo, Wenxuan Wang, Jian Xie +11
Rhombohedral multilayer graphene has emerged as a powerful platform for investigating flat-band-driven correlated phenomena, yet most aspects remain not understood. In this work, w…
Berry Trashcan With Short Range Attraction:Exact Superconductivity in Rhombohedral Graphene
Ming-Rui Li, Yves H. Kwan, Hong Yao +1
We show the presence of analytic superconducting ground states in the Berry Trashcan -- a minimal model of rhombohedral graphene valid for layers -- under s…
