We show how the sign problem occurring in dynamical simulations of random matrices at a nonzero chemical potential can be avoided by judiciously combining matrices into subsets. For each subset the sum of fermionic determinants is real and positive such that importance sampling can be used in Monte Carlo simulations. The number of matrices per subset is proportional to the matrix dimension. We ...

Table 1. Nstd/mod is the sum of supra-threshold voxels (p<0.001 unc., clustersize 5) for different ROIs (see legend below) found in the standard and the modified EPI datasets for the contrasts rewardpunishment, reward-baseline and punishment-baseline. Zstd/mod specifies the maximal Z-score. ROI 1: Insula, ROI 2: Amygdalae, ROI 3: Putamen, ROI 4: Thalamus, ROI 5: Caudate, ROI 6: Parahippocampal ...
