A weak-value interpretation of the Schwinger mechanism of massless/massive pair productions

Abstract (in Japanese) (See Japanese page) 
(in English) According to the Schwinger mechanism, a uniform electric field brings about pair productions in vacuum; the relationship between the production rate and the electric field is different, depending on the dimension of the system. In this paper, we make an offer of another model for the pair productions with weak values: energy fluctuations trigger the pair production, in which a weak value appears as the velocity of a particle. In return to the approximation of the pair production rate, the weak value reveals a new aspect of the pair production. Especially, within the first order, our estimation approximately agrees with the exponential decreasing rate of the Landau-Zener tunneling through the mass energy gap. In other words, such tunneling can be associated with energy fluctuations via the weak value, when the tunneling gap can be regarded as so small due to the high electric field.
