Graphyne as a second-order and real Chern topological insulator in two dimensions
Cong Chen, Weikang Wu, Zhi-Ming Yu +4
Higher-order topological phases and real topological phases are two emerging topics in topological states of matter, which have been attracting considerable research interest. Howe…
Realization of Topological Mott Insulator in a Twisted Bilayer Graphene Lattice Model
Bin-Bin Chen, Yuan Da Liao, Ziyu Chen +4
Magic-angle twisted bilayer graphene has recently become a thriving material platform realizing correlated electron phenomena taking place within its topological flat bands. Severa…
Quantum Many-Body Simulations of the 2D Fermi-Hubbard Model in Ultracold Optical Lattices
Bin-Bin Chen, Chuang Chen, Ziyu Chen +6
Understanding quantum many-body states of correlated electrons is one main theme in modern condensed matter physics. Given that the Fermi-Hubbard model, the prototype of correlated…
Universal Approach to Magnetic Second-Order Topological Insulator
Cong Chen, Zhida Song, Jian-Zhou Zhao +4
We propose a universal practical approach to realize magnetic second-order topological insulator (SOTI) materials, based on properly breaking the time reversal symmetry in conventi…
