Luttinger liquid parameters in one-dimensional Rydberg arrays
Shu-Ao Liao, Li-Ping Yang, Jin Zhang
We investigate Berezinskii-Kosterlitz-Thouless (BKT) transitions in one-dimensional Rydberg chains, where commensurate critical regimes associated with the melting of crystalline o…

The Klein bottle ratio of two-dimensional ferromagnetic Potts models
Zi-Han Wang, Li-Ping Yang
The weakly first-order nature of the two-dimensional 5-state ferromagnetic Potts model poses challenges for numerical study. Using density-matrix and tensor-network renormalization…
