Conductivity in the disordered Hubbard model at half-filling

Nguyen Thi Hai Yen, Hoang Anh Tuan

Institute of Physics

In this work, the optical and dc conductivity for half-filled disordered Hubbard model for various cases in the weak and the intermediate interaction regimes are calculated within the typical medium theory. The influence of random potential and temperature on the optical and dc conductivity in the model is investigated. It is shown that in some cases the disorder can weaken the correlation effect, moves the system away from Mott transition and decreases resistivity of the system.
