Double and Quadruple Flat Bands tuned by Alternative magnetic Fluxes in Twisted Bilayer Graphene

Congcong Le, Qiang Zhang, Cui Fan +2

Twisted bilayer graphene (TBG) can host the moiré energy flat bands with two-fold degeneracy serving as a fruitful playground for strong correlations and topological phases. Howeve…

Ordered and tunable Majorana-zero-mode lattice in naturally strained LiFeAs

Meng Li, Geng Li, Lu Cao +7

Majorana zero modes (MZMs) obey non-Abelian statistics and are considered building blocks for constructing topological qubits. Iron-based superconductors with topological band stru…

Yu-Shiba-Rusinov states in a superconductor with topological Z2 bands

Ching-Kai Chiu, Ziqiang Wang

A Yu-Shiba-Rusinov (YSR) state is a localized in-gap state induced by a magnetic impurity in a superconductor. Recent experiments used an STM tip to manipulate the exchange couplin…

Generalized Fermion Doubling Theorems: Classification of 2D Nodal Systems in Terms of Wallpaper Groups

Congcong Le, Zhesen Yang, Fan Cui +2

The Nielsen-Ninomiya Theorem has set up a ground rule for the minimal number of the topological points in a Brillouin zone. Notably, in the 2D Brillouin zone, chiral symmetry and s…

Dirac Fermion Cloning, Moir Flat Bands and Magic Lattice Constants in Epitaxial Monolayer Graphene

Qiangsheng Lu, Ching-Kai Chiu, Congcong Le +10

Tuning interactions between Dirac states in graphene has attracted enormous interest because it can modify the electronic spectrum of the two-dimensional material, enhance electron…

Fermion doubling theorems in 2D non-Hermitian systems for Fermi points and exceptional points

Zhesen Yang, A. P. Schnyder, Jiangping Hu +1

The fermion doubling theorem plays a pivotal role in Hermitian topological materials. It states, for example, that Weyl points must come in pairs in three-dimensional semimetals. H…
