Puddle-induced sign changes of drag near double neutrality. Here we calculate effective drag resistivity as a function of nA along the line nP = 0 using effective medium theory with negatively correlated puddles. We use the same parameters as in Fig. 4a. We predict this set of crossovers of the sign of drag may be seen in future experiments
