Exact-WKB Analysis of Two-level Floquet Systems
Toshiaki Fujimori, Syo Kamata, Tatsuhiro Misumi +2
We explore the application of the exact Wentzel-Kramers-Brillouin (WKB) analysis to two-level Floquet systems and establish a systematic procedure to calculate the quasi-energy and…
Domain Wall Networks as Skyrmion Crystals in Chiral Magnets
Seungho Lee, Toshiaki Fujimori, Muneto Nitta +1
We theoretically investigate the ground states of a chiral magnet with a square anisotropy and show that it supports domain wall networks as stable ground states. A domain wall jun…
String junctions in flag manifold sigma model
Yuki Amari, Toshiaki Fujimori, Muneto Nitta +1
We numerically construct a stable three-string junction of Y-shape in a flag manifold nonlinear sigma model on .
Moduli Spaces of Instantons in Flag Manifold Sigma Models -- Vortices in Quiver Gauge Theories
Toshiaki Fujimori, Muneto Nitta, Keisuke Ohashi
In this paper, we discuss lumps (sigma model instantons) in flag manifold sigma models. In particular, we focus on the moduli space of BPS lumps in general Kähler flag manifold sig…
Resurgence in 2-dimensional Yang-Mills and a genus altering deformation
Toshiaki Fujimori, Philip Glass
We study resurgence in the context of the partition function of 2-dimensional and Yang-Mills theory on a surface of genus . After discussing the properties of the…
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…
