11:00 - 12:00 Theory Weekly Seminar(TWS)Obtaining the Non-relativistic Quantum Mechanics from Quantum Field Theory: Issues, Folklores, and Facts School PARTICLES AND ACCELERATORS Abstract: Given the classical dynamics of a non-relativistic particle in terms of a Hamiltonian or an action, it is relatively straightforward to obtain the non-relativistic quantum mechanics (NRQM) of the system. These standard procedures, based on either the Hamiltonian or the path integral, however, do not work in the case of a relativistic particle. As a result, we do not have a single particle description of relativistic quantum mechanics (RQM). Instead, the correct approach requires a transmutation of dynamical variables from the position and momentum of a single particle to a field and its canonical momentum. Particles, along with anti ... |
