| Abstract: | A new complete basis set is adopted to solve the single-mode spin-boson model through exact numerical diagonalization.The results show that the use of this basis can significantly simplify the calculation and avoid computing the complicated special functions in the original treatment.Moreover,The evolutions of the corresponding energy levels have been calculated,as well as the tunneling splitting with the environment temperature. |

| Keywords: | spin-boson model macroscopic quantum effect quantum splitting |
