Physics under Ultra-Intense Field with Lasers and Accelerators

Abstract

Interactions between ultra-intense fields and electron beams from accelerators will be much different from what we have observed so far, as incoherent interactions between electrons and laser photons. It is a region where we have not experienced to date as well as where we may encounter a new field of fundamental physics. In this article we introduce examples of interactions between intense fields and electrons and discuss its aspect of fundamental sciences.
