Fig. 5: Extraction of the quantum self-energy.

From: Identification of non-Fermi liquid fermionic self-energy from quantum Monte Carlo data

Fig. 5

The solid dots correspond to the QMC ωnΣ(ωn) for different T, while for each T dataset, the thermal part and a constant α'(T) has been deducted (see Fig. 6). The dashed line corresponds to ωnΣQ(ωn), computed at T = 0, for the bare \(\bar{g}\) from the parameters of section “The lattice model, phase diagram and QMC self-energy”. The gray shaded area is the 95% confidence interval.
