Deconstructing the Gel'fand--Yaglom method and vacuum energy from a theory space
Nahomi Kan, Kiyoshi Shiraishi
The discrete Gel'fand--Yaglom theorem was studied several years ago. In the present paper, we generalize the discrete Gel'fand--Yaglom method to obtain the determinants of mass mat…
Magnetic monopoles in multi-vector boson theories
Koichiro Kobayashi, Nahomi Kan, Kiyoshi Shiraishi
A classical solution for a magnetic monopole is found in a specific multi-vector boson theory. We consider the model whose gauge group is broken by sigma-model fiel…
Analytical Study of Charged Boson Stars with Large Scalar Self-couplings
Nahomi Kan, Kiyoshi Shiraishi
We give good approximate analytic solutions for spherical charged boson stars in the large scalar-self-coupling limit in general relativity. We show that if the charge and mass…
A Newtonian Analysis of Multi-scalar Boson Stars with Large Self-couplings
Nahomi Kan, Kiyoshi Shiraishi
We study solutions for boson stars in the multi-scalar field theory with global symmetry . The properties of the boson stars are investigated by the Newtonian approximati…
