Field theories for Laplacian Growth
Paolo Pisapia, Assaf Shapira, Kay Joerg Wiese
Loop-erased random walks (LERW), the -model at and Laplacian random walks (LRW) are three realizations of the same random process. While this equivalence holds on an…

Bayesian phase transition for the critical Ising model: Enlarged replica symmetry in the epsilon expansion and in 2D
Kay Joerg Wiese, Alapan Das, Adam Nahum
A process that images or measures bond energies in the critical Ising model can be in distinct measurement ``phases'', depending on the precision of measurement. We study the trans…
