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…
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…
Algebraic-Dynamical Perturbation Theory of Large- Hubbard Models. Single Particle Spectrum of Antiferromagnetic Mott Insulating States
Wenxin Ding, Rong Yu
In this work, we present an analytical framework for studying antiferromagnetic (AFM) Mott insulating states in the Hubbard model. We first derive an analytical solution for the si…
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…
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…
