Title |
Classical, QFT, and QED solutions of the Dirac equation |
|
Abstract |
The computational quantum field theory developed by Dr. Su’s
research team provides an effective means for studying the vacuum
breakdown by ultra-strong fields and the generation of electron-positron
pairs with spatial and temporal resolution. With the help of this
computational tool, we were able to comment on the Klein paradox. More
recently, we have focused on how to effectively lower the field
threshold to trigger pair creation by designing external field
configurations with optimal variations in space or in time. We have
extended our model to investigate the origin of the Coulomb force where
electron-proton interactions are facilitated not through an external
background field but through the exchange of mediating photons. The
present talk discusses some results obtained by solving the Dirac
equation from the perspectives of classical mechanics, quantum field
theory, and quantum electrodynamics.
