Virtual turning points and bifurcation of Stokes curves for higher order ordinary differential equations
Takashi Aoki, Takahiro Kawai, Shunsuke Sasaki +2
For a higher order linear ordinary differential operator P, its Stokes curve bifurcates in general when it hits another turning point of P. This phenomenon is most neatly understan…
Quantum Electrodynamics at Large Distances II: Nature of the Dominant Singularities
Henry P. Stapp, Takahiro Kawai
Accurate calculations of macroscopic and mesoscopic properties in quantum electrodynamics require careful treatment of infrared divergences: standard treatments introduce spurious…
Quantum Electrodynamics at Large Distances I: Extracting the Correspondence-Principle Part.
Takahiro Kawai, Henry P. Stapp
The correspondence principle is important in quantum theory on both the fundamental and practical levels: it is needed to connect theory to experiment, and for calculations in the…
Quantum Electrodynamics at Large Distances III: Verification of Pole Factorization and the Correspondence Principle
Takahiro Kawai, Henry P. Stapp
In two companion papers it was shown how to separate out from a scattering function in quantum electrodynamics a distinguished part that meets the correspondence-principle and pole…
