Recent advances of defect-induced spin and valley polarized states in graphene
Yu Zhang, Liangguang Jia, Yaoyao Chen +2
Electrons in graphene have fourfold spin and valley degeneracies owing to the unique bipartite honeycomb lattice and an extremely weak spin-orbit coupling, which can support a seri…
Atomic-Scale Visualization of Chiral Charge Density Wave States and Their Reversible Transition
Xuan Song, Liwei Liu, Yaoyao Chen +13
Chirality is essential for various amazing phenomena in life and matter. However,chirality and its switching in electronic superlattices, such as charge density wave(CDW) arrays, r…
Direct identification of Mott Hubbard band pattern beyond charge density wave superlattice in monolayer 1T-NbSe2
Liwei Liu, Han Yang, Yuting Huang +15
Understanding Mott insulators and charge density waves (CDW) is critical for both fundamental physics and future device applications. However, the relationship between these two ph…
Cellular dynamical mean-field theory study of an interacting topological honeycomb lattice model at finite temperature
Yao-Hua Chen, Hsiang-Hsuan Hung, Guoxiong Su +2
Topological phases originating from spin-orbit coupling have attracted great attention recently. In this work, we use cellular dynamical mean field theory with the continuous-time…
Layer Anti-Ferromagnetism on Bilayer Honeycomb Lattice
Hong-Shuai Tao, Yao-Hua Chen, Heng-Fu Lin +2
Bilayer honeycomb lattice, with inter-layer tunneling energy, has a parabolic dispersion relation, which causes the charge imbalance between two sublattices. Here, we investigate t…
Mott transition and Antiferromagnetic Metal on Shastry-Sutherland Lattice
