Pre-logarithmic and logarithmic fields in a sandpile model
Pre-logarithmic and logarithmic fields in a sandpile model
We consider the unoriented two-dimensional Abelian sandpile model on the half-plane with open and closed boundary conditions, and relate it to the boundary logarithmic conformal field theory with central charge c = −2. Building on previous results, we first perform a complementary lattice analysis of the operator effecting the change …
