Abstract

• Path integral was invented by Feynman as an alternative formulation of quantum mechanics. Feynman formulation of quantum mechanics using the so called path integral is arguably the most elegant. The path formulation of quantum field theory represents the transition amplitude (corresponding to the classical correlation function) as a weighted sum of all possible histories of the system from the initial to the final state. In this work, the full propagation for the propagation of a particle in the one dimensional infinite square well by using the path integral formalism will be obtained by using Feynman’s path integral approach. Visualization of key results is implemented by Mathematica.
