Description
The 2D O(3) model has been widely used as a toy model for quantum chromodynamics and ferromagnetism. It shares fundamental features with quantum chromodynamics, such as being asymptotically free. It is possible to define a trivializing map, a field transformation from a given theory to trivial variables, through a gradient flow. An analytic solution to this trivializing flow may be obtained by a perturbative expansion in the flow parameter. Utilizing this solution allows for new approaches to be considered when proposing updates for a Markov Chain algorithm.
