Canonical quantization

  1. Oct 29, 2015 #1
    Hi all
    I am studying Quantum Field Theory. I read the following statement :"Canonical quantisation is intrinsically not relativistically covariant. Can anyone explain why?. Although everything we did from the beginning was lorentz invariant!!!
    Thank you .

    You are singling out a particular time direction when you introduce the Hamiltonian. This breaks Lorentz covariance.
