Artificial Gauge Field Engineered Excited-State Topology: Control of Dynamical Evolution of Localized Spinons
Jie Ren, Yi-Ran Xue, Run-Jia Luo +2
Spinons are elementary excitations at the core of frustrated quantum magnets. Although it is well-established that a pair of spinons can emerge from a magnon via deconfinement, con…

Exploring quantum criticality and ergodicity-breaking dynamics in spin-1 Kitaev chains via single-ion anisotropies
Wen-Yi Zhang, Qing-Min Hu, Jie Ren +2
We investigate topological gauge-theory terms and quantum criticality in a spin-1 Kitaev chain with general single-ion anisotropies (SIAs). The ground-state phase diagram, includin…
