Two-body wave functions and compositeness from scattering amplitudes. I. General properties with schematic models
Takayasu Sekihara
For a general two-body bound state in quantum mechanics, both in the stable and decaying cases, we establish a way to extract its two-body wave function in momentum space from the…

Quantum Fluctuations of Particles and Fields in Smooth Path Integrals
Takayasu Sekihara
An approach to evaluation of the smooth Feynman path integrals is developed for the study of quantum fluctuations of particles and fields in Euclidean time-space. The paths are des…

New Approach to Continuum Path Integrals for Particles and Fields
Takayasu Sekihara
An approach to approximate evaluation of the continuum Feynman path integrals is developed for the study of quantum fluctuations of particles and fields in Euclidean time-space. Th…
