Time-ordered exponential on the complex plane and Gell-Mann -- Low formula as a mathematical theorem

Shinichiro Futakuchi, Kouta Usui

The time-ordered exponential representation of a complex time evolution operator in the interaction picture is studied. Using the complex time evolution, we prove the Gell-Mann --…
