Boundary Free Energies in Disordered Ising Models
Hexiang Wang, Keheng Zhu, Mauris Chueng
The boundary correction to the free energy of a disordered Ising model depends on the boundary condition, the normalization, and the finite-volume sequence. We give a one-dimension…

Subextensive Random Boundary Perturbations in the Short-Range Edwards--Anderson Model
Hexiang Wang, Keheng Zhu, Mauris Chueng
We consider the nearest-neighbor Edwards--Anderson Ising model on cubic boxes with random perturbations supported at the boundary. We prove that any perturbation admitting an energ…
