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…
Effective field theory of magnon: Dynamics in chiral magnets and Schwinger mechanism
Masaru Hongo, Toshiaki Fujimori, Tatsuhiro Misumi +2
We develop the effective field theoretical descriptions of spin systems in the presence of symmetry-breaking effects: the magnetic field, single-ion anisotropy, and Dzyaloshinskii-…
On exact-WKB analysis, resurgent structure, and quantization conditions
Naohisa Sueishi, Syo Kamata, Tatsuhiro Misumi +1
There are two well-known approaches to studying nonperturbative aspects of quantum mechanical systems: Saddle point analysis of the partition functions in Euclidean path integral f…
Lattice model with twisted boundary condition: bions, adiabatic continuity and pseudo-entropy
Toshiaki Fujimori, Etsuko Itou, Tatsuhiro Misumi +2
We investigate the lattice sigma model on (large) (small) with the symmetric twisted boundary condition, where…
Varieties and properties of central-branch Wilson fermions
Tatsuhiro Misumi, Jun Yumoto
We focus on the four-dimensional central-branch Wilson fermion, which makes good use of six species at the central branch of the Wilson Dirac spectrum and possesses the extra $U(1)…
