introduction

  • U(1) pure gauge theory : theory of light (without matter)\(\mathcal{L}_{\text{free}} = - \frac{1}{4}F_{\mu\nu}F^{\mu\nu}\)
  • quantization of the photon field http://www.ecm.ub.es/~espriu/teaching/classes/fae/LECT4.pdf
    • fix the gauge
    • quantize unconstrained system
    • gives physical and unphysical states (negative norm states)
    • impose the constraint condition to remove negative norm states
    • we get a Hilbert space of physical states



Gupta-Bleuler quantization of QED




remark

  • if matter exists, we get QED\(\mathcal{L}_{\text{free}} = \bar{\psi} (i\gamma^\mu \partial_\mu -m)\psi - \frac{1}{4}F_{\mu\nu}F^{\mu\nu}\)
