Topological Blocking of the Schwinger Effect in the Salpeter Equation: A Lefschetz Thimble Analysis
Yutaro Shoji
We present a comprehensive Lefschetz thimble analysis of the one-dimensional Salpeter equation under a strong electric field. By treating the non-local square-root operator within…
Symmetry of Bounce Solutions at Finite Temperature
Yutaro Shoji, Masahide Yamaguchi
The seminal work of Coleman, Glaser, and Martin established that, at zero temperature, any non-trivial solution to the equations of motion with the least Euclidean action is …
Stable Evaluation of Lefschetz Thimble Intersection Numbers: Towards Real-Time Path Integrals
Yutaro Shoji, Katarina TrailoviÄ
We introduce a robust numerical method for determining intersection numbers of Lefschetz thimbles in multivariable settings. Our approach employs the multiple shooting method to so…
A novel realization of linear seesaw model in a non-invertible selection rule with the assistance of symmetry
Hiroshi Okada, Yutaro Shoji
We propose a novel realization of linear seesaw model in a non-invertible selection rule with the assistance of symmetry. In our framework, Dirac mass matrices are ge…
Regularization of Functional Determinants of Radial Operators via Heat Kernel Coefficients
Yutaro Shoji, Masahide Yamaguchi
We propose an efficient regularization method for functional determinants of radial operators using heat kernel coefficients. Our key finding is a systematic way to identify heat k…
