In classical mechanics I would say:
a particle can have any initial position and velocities, Newton laws give you the evolution of the particle:
F=ma , is the basic equation, if you know the forces acting on the particle by solving this equation you get the future values for velocity and position
In quantum mechanics:
The "particle" is characterized by a wavefunction that can be used to calculate the probability of finding the particle at certain position or momentum.
If you know the wavefunction you plug it into the Schrodinger equation and you get the evolution on time of this wavefunction.
Can anybody tell me a similar basic scheme for quantum field theory? For example, in QED, Is there a basic differential equation? What about QCD?
Thanks for your time.
