Description
Critical slowing down is one of the major difficulties in lattice QCD. Recently, it is becoming an urgent problem in the field as the precision goal is getting high and small lattice spacings have become demanding. As a promising approach towards conquering this problem, we here study the idea of the trivializing map, proposed by Luscher. In particular, we study the properties of the map at large beta using a toy model, and discuss how conventional approximations are insufficient to realize the triviality. We also consider possible strategies to circumvent the obstacles.
