Hierarchical Trion Formation and Fractionalized Solitons in One Dimension
Yan-Guang Yue, Qi Song, Jie Lou +1
Stabilizing commensurate trions in one-dimensional quantum mixtures is typically hindered by phase separation. Within the conventional density-driven framework, the asymmetri…

Universal Rule for Topological Hopf Term via Dirac-Spin Coupling
Yan-Guang Yue, Shuai Yang, Zheng-Xin Liu +1
It is known that the topological Hopf term in two-dimensional (2D) spin systems can be derived by coupling to massless Dirac fermions. We establish a universal rule governing the g…

Microscopic study of 3D Potts phase transition via Fuzzy Sphere Regularization
Shuai Yang, Yan-Guang Yue, Yin Tang +3
The Potts model describes interacting spins with different components, which is a direct generalization of the Ising model (). Compared to the existing exact solutions in…
