All-order Resurgence from Complexified Path Integral in a Quantum Mechanical System with Integrability
Toshiaki Fujimori, Syo Kamata, Tatsuhiro Misumi +2
We discuss all-order transseries in one of the simplest quantum mechanical systems: a U(1) symmetric single-degree-of-freedom system with a first-order time derivative term. Follow…
Resurgence and semiclassical expansion in two-dimensional large- sigma models
Hiromichi Nishimura, Toshiaki Fujimori, Tatsuhiro Misumi +2
The resurgence structure of the 2d sigma model at large is studied with a focus on an IR momentum cutoff scale that regularizes IR singularities in the semiclassical…
SM gauge fields localized on non-Abelian vortices in 6 dimensions
Masato Arai, Filip Blaschke, Minoru Eto +2
A brane-world GUT model with global non-Abelian vortices is constructed in six-dimensional spacetime. We find a solution with a vortex associated to separated from…
Quantum phase transition and Resurgence: Lessons from 3d SQED
Toshiaki Fujimori, Masazumi Honda, Syo Kamata +3
We study a resurgence structure of a quantum field theory with a phase transition to uncover relations between resurgence and phase transitions. In particular, we focus on three-di…
Exact WKB analysis of the vacuum pair production by time-dependent electric fields
Hidetoshi Taya, Toshiaki Fujimori, Tatsuhiro Misumi +2
We study the vacuum pair production by a time-dependent strong electric field based on the exact WKB analysis. We identify the generic structure of a Stokes graph for systems with…
The Volume of the Quiver Vortex Moduli Space
Kazutoshi Ohta, Norisuke Sakai
We study the moduli space volume of BPS vortices in quiver gauge theories on compact Riemann surfaces. The existence of BPS vortices imposes constraints on the quiver gauge theorie…
