Interaction-driven spontaneous broken-symmetry insulator and metals in ABCA tetralayer graphene
Kai Liu, Jian Zheng, Yating Sha +11
Interactions among charge carriers in graphene can lead to the spontaneous breaking of multiple degeneracies. When increasing the number of graphene layers following rhombohedral s…
Tuning electronic properties in transition metal dichalcogenides MX (M= Mo/W, X= S/Se) heterobilayers with strain and twist angle
Ravina Beniwal, M. Suman Kalyan, Nicolas Leconte +3
We explore the direct to indirect band gap transitions in MX (M= Mo/W, X= S/Se) transition metal dichalcogenides heterobilayers for different system compositions, strains, and…
Topological flat bands in rhombohedral tetralayer and multilayer graphene on hexagonal boron nitride moire superlattices
Youngju Park, Yeonju Kim, Bheema Lingam Chittari +1
We show that rhombohedral four-layer graphene (4LG) nearly aligned with a hexagonal boron nitride (hBN) substrate often develops nearly flat isolated low energy bands with non-zero…
Chirality and correlations in the spontaneous spin-valley polarization of rhombohedral multilayer graphene
Yunsu Jang, Youngju Park, Jeil Jung +1
We investigate the total energies of spontaneous spin-valley polarized states in bi-, tri-, and tetralayer rhombohedral graphene where the long-range Coulomb correlations are accou…
Commensuration torques and lubricity in double moire systems
Nicolas Leconte, Youngju Park, Jiaqi An +1
We study the commensuration torques and layer sliding energetics of alternating twist trilayer graphene (t3G) and twisted bilayer graphene on hexagonal boron nitride (t2G/BN) that…
Electronic structure of biased alternating-twist multilayer graphene
Kyungjin Shin, Yunsu Jang, Jiseon Shin +2
We theoretically study the energy and optical absorption spectra of alternating twist multilayer graphene (ATMG) under a perpendicular electric field. We obtain analytically the lo…
