We study, by means of the density-matrix renormalization group (DMRG) technique, the evolution of the ground state in a one-dimensional topological insulator, from the …
The book reviews several theoretical, mostly exactly solvable, models for selected systems in condensed states of matter, including the solid, liquid, and disordered states, and for …

We propose that ultracold alkaline-earth-like atoms confined in one-dimensional optical lattice can realize a Kondo lattice model which hosts a symmetry-protected topological (SPT) …
Y Araki, D Suenaga, K Suzuki, S Yasui - Physical Review Research, 2021 - APS
We investigate two different types of relativistic Kondo effects, distinguished by heavy- impurity degrees of freedom, by focusing on the energy-momentum dispersion relations of …
We investigate the ground state of ap-wave Kondo-Heisenberg model introduced by Alexandrov and Coleman with an Ising-type anisotropy in the Kondo interaction and …
Motivated by experiments on the organic compound (Per) 2 [Pt (mnt) 2], we study the ground state of the one-dimensional Kondo lattice model at quarter filling with the density matrix …
R Masui, K Totsuka - Physical Review B, 2022 - APS
We study higher-spin (S≥ 1) generalization of the one-dimensional Kondo-Heisenberg model, in which the local spin-S moments of the Kondo-lattice model interact with each other …
Y Zhong, Q Wang, Y Liu, HF Song, K Liu, HG Luo - Frontiers of Physics, 2019 - Springer
In recent years, interacting topological insulators have emerged as new frontiers in condensed matter physics, and the hotly studied topological Kondo insulator (TKI) is one of …
We study the nonequilibrium dynamics of a one-dimensional topological Kondo insulator, modelled by ap-wave Anderson lattice model, following a quantum quench of the on-site …
