We derive dynamical, real time radiation reaction effects from lightfront QED. Combining the
Hamiltonian formalism with a plane wave background field, the calculation is performed in …

We investigate the quantum effect on the Larmor radiation from a moving charge in an
expanding universe based on the framework of the scalar quantum electrodynamics. A …

We investigate the radiation of an inertial scalar particle evolving in a de Sitter (dS)
expanding Universe. In the context of scalar QED, the process is generated by the first-order …

First-order quantum correction to the Larmor radiation is investigated on the basis of the
scalar QED on a homogeneous background of a time-dependent electric field, which is a …

We study the one-photon scalar pair production QED process on the expanding de Sitter
spacetime. Using perturbation theory, we obtain the transition probability and study its …

We extend our previous work [Phys. Rev. D 83, 045030 (2011)], which investigated the first-
order quantum effect in the Larmor radiation from a moving charge in a spatially …

A bstract A classical computation of vector bremsstrahlung in ultrarelativistic gravitational-
force collisions of massive point particles is presented in an arbitrary number d of extra …

We consider first-order transition amplitudes in external fields in QED in the expanding de
Sitter space and point out that they are gauge dependent quantities. We examine the gauge …

Based on a suitable linear combination of the physical and un-physical electromagnetic
potentials, the radiation reaction potentials have been calculated. Through the near zone …

This thesis is a report of work which develops the study of electromagnetic radiation by
accelerating charges in the scalar quantum electrodynamic theory. We investigate aspects …
