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 Ground States and Domain Walls in One Dimensional Chiral Magnets
Calum Ross, Norisuke Sakai, Muneto Nitta
We determine exactly the phase structure of a chiral magnet in one spatial dimension with the Dzyaloshinskii-Moriya (DM) interaction and a potential that is a function of the third…
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…
