Nature of ground state incongruence in two-dimensional spin glasses

Research output: Contribution to journalArticle


We rigorously rule out the appearance of multiple domain walls between ground states in 2D Edwards-Anderson Ising spin glasses (with periodic boundary conditions and, e.g., Gaussian couplings). This supports the conjecture that there is only a single pair of ground states in these models.
