We present precise values of the dipole polarizabilities (alpha) of the ground [4f(14)6s] S-2(1/2) andmetastable [4f(14)5d] D-2(3/2) states of Yb+, that are important in reducing systematics in the clock frequency of the [4f(14)6s] S-2(1/2) -> [4f(14)5d] D-2(3/2) transition. The static values of a for the ground and [4f(14)5d] D-2(3/2) states are estimated to be 9.8(1) x 10(-40) J m(2) V-2 and 17.6(5) x 10(-40) J m(2) V-2, respectively, while the tensor contribution to the [4f(14)5d] D-2(3/2) state as -12.3(3) x 10(-40) J m(2) V-2 compared to the experimental value -13.6(22) x 10(-40) J m(2) V-2. This corresponds to the differential scalar polarizability value of the above transition as -7.8 (5) x 10(-40) J m(2) V-2 in contrast to the available experimental value -6.9(1.4) x 10(-40) Jm(2)V(-2). This results in the black- body radiation shift of the clock transition as - 0.44(3) Hz at the room temperature, which is large as compared to the previously estimated values. Using the dynamic a values, we report the tune- out and magic wavelengths that could be of interest to subdue systematics due to the Stark shifts and for constructing lattice optical clock using Yb+.
