Topological phases in N-layer ABC-graphene boron-nitride moire superlattices
David Andres Galeano Gonzalez, Bheema Lingam Chittari, Youngju Park +2
Rhombohedral trilayer graphene on hexagonal boron nitride (TLG/BN) hosts gate-tunable, valley-contrasting, nearly flat topological bands that can trigger spontaneous quantu…
Electron-hole asymmetry and band gaps of commensurate double moire patterns in twisted bilayer graphene on hexagonal boron nitride
Jiseon Shin, Youngju Park, Bheema Lingam Chittari +1
Spontaneous orbital magnetism observed in twisted bilayer graphene (tBG) on nearly aligned hexagonal boron nitride (BN) substrate builds on top of the electronic structure resultin…
Lifshitz phase transitions in one-dimensional Gamma model
Zi-An Liu, Tian-Cheng Yi, Jin-Hua Sun +2
In this paper, we study quantum phase transitions and magnetic properties of a one-dimensional spin-1/2 Gamma model, which describes the off-diagonal exchange interactions between…
Topological flat bands without magic angles in massive twisted bilayer graphenes
Srivani Javvaji, Jinhua Sun, Jeil Jung
Twisted bilayer graphene (TBG) hosts nearly flat bands with narrow bandwidths of a few meV at certain {\em magic} twist angles. Here we show that in twisted gapped Dirac material b…
Spatial anisotropy of Kondo screening cloud in a type-II Weyl semimetal
Lu-Ji Wang, Xing-Tai Hu, Lin Li +3
We theoretically study the Kondo screening of a spin-1/2 magnetic impurity in the bulk of a type-II Weyl semimetal (WSM) by use of the variational wave function method. We consider…
Single Magnetic Impurity in Tilted Dirac Surface States
Jin-Hua Sun, Lu-Ji Wang, Xing-Tai Hu +2
We utilize variational method to investigate the Kondo screening of a spin-1/2 magnetic impurity in tilted Dirac surface states with the Dirac cone tilted along the -axis. We…
