Localization Tensor Revisited: Geometric-Probabilistic Foundations and a Structure-Factor Criterion under Periodic Boundaries
Zhe-Hao Zhang, Xiaoming Cai, Yi-Cong Yu
We revisit the localization tensor (LT) from geometric and probabilistic perspectives and construct extensions that are naturally compatible with periodic boundary conditions (PBC)…

Kaleidoscope Yang-Baxter Equation for Gaudin's Kaleidoscope models
Wen-Jie Qiu, Xi-Wen Guan, Yi-Cong Yu
Recently, researchers have proposed the Asymmetric Bethe ansatz method - a theoretical tool that extends the scope of Bethe ansatz-solvable models by "breaking" partial mirror symm…

Observation of non-Hermitian boundary induced hybrid skin-topological effect excited by synthetic complex frequencies
Tianshu Jiang, Chenyu Zhang, Ruo-Yang Zhang +6
The hybrid skin-topological effect (HSTE) has recently been proposed as a mechanism where topological edge states collapse into corner states under the influence of the non-Hermiti…
