Scaling Theory for Learning Low-Energy Quantum Subspaces
Guijing Duan, Chen Mo, Di Luo
Phase diagrams and energy surfaces require low-energy states across a family of Hamiltonians, but solving each parameter point independently is prohibitively expensive. An importan…
Cascade of Spin Liquids in a Bilayer Triangular-lattice Antiferromagnet Rb_2Co_2(SeO_3)_3
Xiaoyu Xu, Yunlong Wang, Xuejuan Gui +20
In frustrated Ising magnets, classical spin liquids (CSLs) with macroscopic ground-state degeneracy can survive against conventional magnetic order, as exemplified by systems on tr…
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…
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…
Spin excitations of the Shastry-Sutherland model -- altermagnetism and deconfined quantum criticality
Hongyu Chen, Guijing Duan, Changle Liu +4
Frustrated quantum magnets can host a variety of exotic spin excitations, including fractionalized spin excitations coupled to emergent gauge fields at deconfined quantum critical…
Evidence for field induced quantum spin liquid behavior in a spin-1/2 honeycomb magnet
Gaoting Lin, Mingfang Shu, Qirong Zhao +16
One of the most important issues in modern condensed matter physics is the realization of fractionalized excitations, such as the Majorana excitations in the Kitaev quantum spin li…
Theory of magnetism for rare-earth magnets on the Shastry-Sutherland lattice with non-Kramers ions
Guijing Duan, Rong Yu, Changle Liu
Motivated by the rapid experimental progress on the rare-earth Shastry-Sutherland lattice magnets, we propose a generic effective spin model that describes interacting non-Kramers…
