Bi-local fields interacting with a constant electric field and related problems including the Schwinger effect
Kenichi Aouda, Naohiro Kanda, Shigefumi Naka +1
The bi-local fields are the quantum fields of two-particle systems, the bi-local, systems, bounded by relativistic potentials. Since those form constrained dynamical systems, it is…
A classical mechanical model of two interacting massless particles in de Sitter space and its quantization
Naohiro Kanda, Satoshi Okano
A conformally invariant model of two interacting massless particles in Minkowski space was proposed by Casalbuoni and Gomis [1]. We generalize this model to the case of de Sitter s…
Ladder Operators in Repulsive Harmonic Oscillator with Application to the Schwinger Effect
Kenichi Aouda, Naohiro Kanda, Shigefumi Naka +1
The ladder operators in harmonic oscillator are a well-known strong tool for various problems in physics. In the same sense, it is sometimes expected to handle the problems of repu…
An Approach to Yukawa's Elementary Domain Based on $\mbox{AdS}_5$ Spacetime
Kenichi Aouda, Naohiro Kanda, Shigefumi Naka +1
The field equations of elementary domains proposed by Yukawa in 1968 are studied from the viewpoint of particle embedded $\mbox{AdS}_5$ spacetime with warp factor. The fifth dimens…
Bi-Local Field in Gravitational Shock Wave Background
Naohiro Kanda, Shigefumi Naka
The particles with almost light velocity are able to be sources of the shock-wave gravity (SWG). Then, for ultra-high-energy particles, there exist two-body scatterings such that o…
New Renormalization Scheme of Vacuum Polarization in QED
T. Fujita, N. Kanda, H. Kato +4
We examine the vacuum polarization contribution in the renormalization scheme of QED. Normally, the quadratic divergence term is discarded under the condition that the counter term…
