Non-monotonic temperature dependence of thermopower in strongly correlated electron systems

By M. Matsuo, S. Okamoto, W. Koshibae, M. Mori and S. Maekawa


We examine the temperature dependence of thermopower in the single band Hubbard model using dynamical mean-field theory. The strong Coulomb interaction brings about the coherent-to-incoherent crossover as temperature increases. As a result, the thermopower exhibits non-monotonic temperature dependence and asymptotically approaches values given by the Mott-Heikes formula. In the light of our theoretical result, we discuss the thermopower in some transition metal oxides. The magnetic field dependence of the thermopower is also discussed.Comment: 4 pages, 4 figure
