Quantum Entanglement of Bethe States
Yu Hao, Yunfeng Jiang, Bi-Quan Yang +1
We investigate the quantum entanglement of Bethe states across a family of integrable spin chains, including the XXX model, its higher-spin generalizations (XXX…

Mesons in a quantum Ising ladder
Yunjing Gao, Yunfeng Jiang, Jianda Wu
When two transverse-field Ising chains (TFICs) with magnetic order are coupled, the original free excitations become confined, giving rise to meson-like bound states. In this work,…
