Altermagnetism in exactly solvable model: the Ising-Kondo lattice model
Miaomiao Zhao, Wei-Wei Yang, Yin Zhong
Altermagnet (AM), a recently identified class of collinear magnet, has garnered significant attention due to its unique combination of zero net magnetization and spin-split energy…
Topic Review: Hatsugai-Kohmoto models: Exactly solvable playground for Mottness and Non-Fermi Liquid
Miaomiao Zhao, Wei-Wei Yang, Yin Zhong
This pedagogic review aims to give a gentle introduction to an exactly solvable model, the Hatsugai-Kohmoto (HK) model, which has infinite-ranged interaction but conserves the cent…
Demystifying strange metal and violation of Luttinger theorem in a doped Mott insulator
Wei-Wei Yang, Yin Zhong, Hong-Gang Luo
Metallic states coined strange metal (SM), with robust linear- resistivity, have been widely observed in many quantum materials under strong electron correlation, ranging from h…
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…
