High Energy Particle Production from Proton Synchrotron Radiation in Strong Magnetic Fields in Relativistic Quantum Field Theory
Tomoyuki Maruyama, A. Baha Balantekin, Myung-Ki Cheoun +4
We investigate photon, pion, and rho-meson production from proton synchrotron radiation in the presence of strong magnetic fields. The proton decay widths and the luminosities of t…

Axial-Vector and Tensor Spin Polarization and Chiral Restoration in Quark Matter
Tomoyuki Maruyama, Toshitaka Tatsumi
We study spontaneous spin-polarizations of quark matter with flavour symmetry at zero temperature in the NJL model. In a relativistic framework, there are two types of the…

Photon vortex generation from nonlinear Compton scattering in Feynman approach
Tomoyuki Maruyama, Takehito Hayakawa, Ryoichi Hajima +2
In the present study, we show calculation of nonlinear Compton scattering with circularly polarized photons in a cylindrical coordinate using Feynman diagram to calculate photon vo…
