摘要：
We investigate the thermoelectric properties of a system near a pressure-driven Mott-Hubbard transition. The dependence of the thermopower and the figure of merit on pressure and temperature within a degenerate Hubbard model for integer filling n = 1 is calculated using dynamical mean-field theory. The quantum Monte Carlo method is used to solve the impurity model. Obtained results can qualitatively explain thermoelectric properties of various strongly correlated materials.
