Fig. 1: Comparison of simulated and experimental thermopower.
From: Quantitative assessment of the universal thermopower in the Hubbard model
Thermopower S as a function of doping p from DQMC simulations (empty markers connected by lines), compared with doping dependence of S for various cuprates at T = 290 K (solid scattered markers, data from refs. 9,11). For U/t = 8 and \({t}^{{\prime} }/t=0\), the temperature is kBT = t/3.5. For U/t = 6, the temperature is kBT = t/4 for both \({t}^{{\prime} }/t=0\) and \({t}^{{\prime} }/t=-0.25\).
