| 中文摘要 | We study the critical behavior of the single-site entanglement entropy S at the Mott metal-insulator transition in infinite-dimensional Hubbard model. For this model, the entanglement between a single site and rest of the lattice can be evaluated exactly, using the dynamical mean-field theory (DMFT). Both the numerical solution using exact diagonalization and the analytical one using two-site DMFT gives S-S-c proportional to alpha log(2)[(1/2-D-c)/D-c](U - U-c), with D-c the double occupancy at U-c and alpha < 0 being different on two sides of the transition. |
