Resurgence like method and higher corrections of bounce calculation

Speakers

  • Mr. Naohisa SUEISHI

Description

Resurgence is a method to connect perturbative series with nonperturbative effect via Stokes phenomenon. In resurgence, Borel ambiguity should be cancelled but in bounce calculation, which shows the path integral itself has ambiguity, as a result we can the Borel ambiguity regarded as the bounce contribution itself. With this relation, I calculated higher corrections of bounce contribution from the perturbative series and check it with the behaviour of the wave function.
