Optimal Mixing Time for the Ising Model in the Uniqueness Regime

Xiaoyu Chen, Weiming Feng, Yitong Yin +1

We prove an optimal $O (n lo g n)$ mixing time of the Glauber dynamics for the Ising models with edge activity $β \in (\frac{Δ - 2}{Δ}, \frac{Δ}{Δ - 2})$ . This mixing time bound h…

Rapid mixing of Glauber dynamics via spectral independence for all degrees

Xiaoyu Chen, Weiming Feng, Yitong Yin +1

We prove an optimal $Ω (n^{- 1})$ lower bound on the spectral gap of Glauber dynamics for anti-ferromagnetic two-spin systems with $n$ vertices in the tree uniqueness regime. This sp…
