Relativistic Quantum Dynamics

Written by: Eugene V. Steganovich

Eugene V. Steganovich is one of those educators who can share a vast work experience with his students. He has a Ph.D degree in Physics and Mathematics from the University of Latvia and over 16 years professional experience with Synopsys, Inc.

Please forgive me as this is way above my head so I have quoted a bit liberally from Stefanovich’s website to provide this brief explanation of his textbook…

“Unification of quantum mechanics and the principle of relativity was one of the most desired goals in theoretical physics of the 20th century.” His online textbook explains a “new relativistic quantum theory of charged particles and their interactions,” which is called “Relativistic quantum dynamics” or RQD.

This is a truly living textbook as it has been updated 17 times since it was first published in 2005. When I added it to the Free Textbook List, the last update had been posted on 16 February 2015.

NOTE: Remnants of a personal website for Steganovish can be found here – Oddly enough, the link to his own textbook no longer works but the links to his 6 articles on this topic appear to be functional.
