Wikipedia

  1. Propagator

    In quantum mechanics and quantum field theory, the propagator is a function that specifies the probability amplitude for a particle to travel from one place to another in a given period of time, or to travel with a certain energy and momentum. In Feynman diagrams, which serve to calculate the rate of collisions in quantum field theory, virtual particles contribute their propagator to the rate of the scattering event described by the respective diagram. These may also be viewed as the inverse of the wave operator appropriate to the particle, and are, therefore, often called (causal) Green's functions (called "causal" to distinguish it from the elliptic Laplacian Green's function).

  1. propagator

    In physics, particularly in the field of quantum mechanics, a propagator is a mathematical function or operator that gives the probability amplitude for a particle to move from one place to another in a certain period of time, considering both its velocity and direction of movement. It describes the behavior of quantum particles when they evolve over time. The propagator is used in theories such as quantum electrodynamics and quantum field theory.

Webster Dictionary

  1. Propagatornoun

    one who propagates; one who continues or multiplies

  2. Etymology: [L.: cf. F. propagateur.]

  1. 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. Propagators are used to represent the contribution of virtual particles on the internal lines of Feynman diagrams. They also can be viewed as the inverse of the wave operator appropriate to the particle, and are therefore often called Green's functions.
