FRSB in the SK spin glass: convergence to full-interval support at zero temperature

Hong-Bin Chen

We prove full replica symmetry breaking for the zero-field Sherrington-Kirkpatrick model at zero temperature: the Parisi minimizer is absolutely continuous, has a smooth density, a…

Multi-point functions of a full-plane two-state fuzzy $4$ -Potts model

Hong-Bin Chen, Jiaming Xia

We study the full-plane two-state fuzzy $4$ -Potts model, obtained by assigning independent balanced ${\pm 1}$ spins to the open clusters of a critical $q = 4$ random-cluster configu…

Critical exponents for planar random-cluster model with cluster-weight $q = 4$

Hong-Bin Chen, Hugo Duminil-Copin, Tiancheng He +4

Using the Baxter-Kelland-Wu coupling and the convergence of the height function of the six-vertex model to the Gaussian Free Field, we extract critical exponents for the planar cri…
