Hexagon Ising-Kondo lattice: An implication for intrinsic antiferromagnetic topological insulator
Wei-Wei Yang, Yin Zhong, Hong-Gang Luo
Recently, the MnBiTe material has been proposed as the first intrinsic antiferromagnetic topological insulator (AFMTI), where the interplay between magnetism and topology i…
Hidden Anderson Localization in Disorder-Free Ising-Kondo Lattice
Wei-Wei Yang, Lan Zhang, Xue-Ming Guo +1
Anderson localization (AL) phenomena usually exists in systems with random potential. However, disorder-free quantum many-body systems with local conservation can also exhibit AL o…
Exactly Solvable Kondo Lattice Model in Anisotropic Limit
Wei-Wei Yang, Jize Zhao, Hong-Gang Luo +1
In this paper we introduce an exactly solvable Kondo lattice model without any fine-tuning local gauge symmetry. This model describes itinerant electrons interplaying with a locali…
