... to be compared with eq. 2. Such pairs of coupled differential equations for two functions, one having a (-) sign, the other a (+) sign, are called symplectic, or ‘area preserving.’ Classically this means an area xp is mapped into an equal area in phase space at a later time. Quantum mechanically i ...

... 1. Consider a free non-relativistic particle of mass m. In the lecture we assumed the time evolution of each Fourier component of a matter wave ψ(x, t) was given by ei(kx−ω(k)t) corresponding to a right moving wave if k, ω(k) were of the same sign. We could equally well have considered the time evol ...

Propagator

In quantum mechanics and quantum field theory, the propagator gives the probability amplitude for a particle to travel from one place to another in a given time, or to travel with a certain energy and momentum. In Feynman diagrams, which calculate the rate of collisions in quantum field theory, virtual particles contribute their propagator to the rate of the scattering event described by the diagram. They also can be viewed as the inverse of the wave operator appropriate to the particle, and are therefore often called Green's functions.
