Relativity and Quantum Mechanics

"Relativistic Quantum Mechanics (RQM) is any Poincare covariant formulation of Quantum Mechanics (QM). This theory is applicable to massive particles propagating at all velocities up to those comparable to the speed of light c, and can accommodate massless particles. The theory has application in high energy physics, particle physics and accelerator physics, as well as atomic physics, chemistry and condensed matter physics. Though, RQM is only an approximation to a fully self-consistent relativistic theory of known particle interactions because it does not describe cases where the number of particles changes. This book envisages the theory of relativity and quantum mechanics."
