Generalized Holstein-Primakoff transformation with optimizable bosonic truncation
Yang Liu, Jia-Wei Mei, Rong Yu +3
Spin-wave theory provides a quasiparticle description of excitation spectra in quantum spin systems. In this theory, the spin operators are usually bosonized by the Holstein-Primak…
Quasi-one-dimensional spin excitations in the iron pnictide NaFeCuAs
Yifan Wang, David W. Tam, Weiyi Wang +8
Spectroscopic measurements in model one-dimensional (1D) correlated systems offer insights for understanding their two-dimensional counterparts, which include the cuprate and iron…
Emergence of Kugel-Khomskii physics in quarter-filled bilayer correlated systems
Guijing Duan, Yunlong Wang, Zhiguang Liao +2
We present a theoretical study of the low-energy physics of a quarter-hole-filled two-orbital bilayer Hubbard model motivated by transition-metal bilayer systems with strong orbita…
Single-layer framework of variational tensor network states
Hongyu Chen, Yangfeng Fu, Weiqiang Yu +2
We propose a single-layer tensor network framework for the variational determination of ground states in two-dimensional quantum lattice models. By combining the nested tensor netw…
Spinons, solitons and random singlets in the spin-chain compound copper benzoate
Ying Chen, Guijing Duan, Yuejiu Zhao +15
The antiferromagnetic Heisenberg chain is a paradigmatic quantum system hosting exotic excitations such as spinons and solitons, and forming random singlet state in the pre…
Theory of rare-earth Kramers magnets on a Shastry-Sutherland lattice: dimer phases in presence of strong spin-orbit coupling
Changle Liu, Guijing Duan, Rong Yu
Shastry-Sutherland magnet is a typical frustrated spin system hosting rich phases. While the Heisenberg limit has been extensively studied, the role of spin-orbit coupling is not w…
