| 英文摘要 | The periodic instanton method is used to study the decay rates of metastable ground state and excited states of the cubic potential. the imaginary part of the energy is calculated through the standard procedure in the path-integral scheme. a formula of the decay rate valid for the entire region of energy is obtained. this formula provides a linkage between classical thermal activation at high temperatures and purely quantum tunneling at zero temperature. it is shown that in the low energy limit this more general result reduces exactly to the vacuum result. the temperature dependence of the decay rate agrees with earlier works in the literature. |
