Description
We study and visualize the process of topology change in field transformation hybrid Montecarlo, correlating gauge and fermion forces with changes in the chiral mode structure of the Domain Wall fermion operator. We see that in each trajectory there are multiple changes of topology by both flowed gauge measures and by the Domain wall fermion index. These appear to correspond to small scale gauge structures and rapid localized reversion. This suggests both a mechanism how the FTHMC heuristic may help address tunneling rates, and perhaps could lead to improved formulations of the algorithm
