| Abstract: | We study the bosonic pair creation from the vacuum by an external force field of arbitrary strength and shape in space and time. Our approach is similar to the computational quantum field theory developed for fermions. The non-perturbative solutions enable us to study the single and multiple boson-antiboson pair dynamics. The closed-form analytical expressions are based on the set of solutions to the time dependent Klein-Gordon equation that may be obtained numerically. In contrast to the dynamics for electron/positron pairs, the boson pair creation is not limited by the Paul exclusion principle and reveals an enhancement of the vacuum’s decay rate. |
