Topological Susceptibility of the 2d O(3) Model under Gradient Flow
The 2D O(3) model is widely used as a toy model for ferromagnetism and for quantum chromodynamics. With the latter it shares—among other basic aspects—the property that the continuum functional integral splits into topological sectors. Topology can also be defined in its lattice regularized version,...
