Quantum Field Theory

  • Jakob SchwichtenbergEmail author
Part of the Undergraduate Lecture Notes in Physics book series (ULNP)


In this chapter the framework of quantum field theory is introduced. Starting with the equation derived in Chap. 5\( \left[ {{\Phi} (x),\pi (y)} \right] = i\delta \left( {x - y} \right), \)we are able to see that the fields itself are operators. The solutions to the equations of motion for spin 0, 1/2 and 1 are written in terms of their Fourier expansions.
